Product overview
The T68i comes in two versions, T68i and T68ie.
Theonlydifferencebetweenthetwoversionsis
the languages they support. In this document, the
name T68i stands for both versions.
The T68i is small, sleek and impressively
designed. The most innovative of its features is a
large 256 colour display allowing high-quality
colour imaging and a host of new interfaceenhancing functions.
With a GPRS (General Packet Radio Services)
modem built in, the T68i offers a fast and
satisfying mobile Internet experience. And with
Bluetooth wireless technology, connecting the
T68i to other devices is smooth and simple. The
T68i is a triple band 900/1800/1900 premium
product which is planned to be available Q1,
2002.
Key functions and features
Multimedia Messaging - Digital
greetings
Reactingtotheenormouspopularityofmobile
phone messaging, Sony Ericsson has
incorporated the latest messaging standard into
the T68i, along with a colour display for an
enhanced imaging experience.
Say it in words, say it with pictures, animate it,
add sound. Multimedia birthday and holiday
greetings are great fun to put together using the
T68i. On vacation, use your mobile phone and
accessories to send a digital postcard with
stylized text, digital pictures of where you are,
and authentic sound clips to friends and family
back home. If, when shopping, you find
something a friend might like, you can instantly
send a digital picture of the item and ask if they
like it.
With MMS, the subscription applications get
more interesting, for example stock information,
movie trailers and weather reports
Imaging
With a digital camera attached to your T68i, you
can take, view, store and send high-quality
pictures over the air to another mobile phone, as
MMS messages, or you can send them to an email address or Web photo album. Downloading
images from the Web is another alternative.
Thousands of online image collections already
exist on the Web and many sites are already
gearing up to include images for use in mobile
phones.
There are various ways to incorporate images and
other multimedia into your communication. You
can attach pictures to people listed in your phone
book and have pictures or icons of the caller
identifying them in your display.
The pictures are stored in the picture browser in
the phone. From here, the user can select view,
thumbnail or full view, as well as keep track of the
number and size of the pictures stored in the
phone.
WAP 2.0 supporting XHTML™
The WAP browser supports the markup
languages of WAP 2.0 – XHTML Mobile and
XHTML Basic. These two subsets of the Web
standard XHTML are supported by all major Web
browsers. An XHTML page can be viewed in both
the WAP browser and in any standard Web
browser. All of the basic XHTML features are
supported, including text, images, links,
checkboxes, radio buttons, text areas, headings,
horizontal rules and lists.
In addition to XHTML, the WAP browser supports
WML. The user can navigate between WML and
XHTML pages.
WAP 2.0 in the T68i also supports cookies, often
used by Web sites to store site-specific
information in the browser between visits to the
site. Cookies are often used by e-commerce sites
(shopping carts and wish lists), and to save the
user from entering the same information more
than once.
Full graphic 256 colour display
The large colour display of the T68i enhances
viewing, facilitating high-quality multimedia
messaging and personalized imaging. The
standby display looks like the desktop in a
computer, with the menus presented as icons.

Joystick navigation
The T68i has an easy-to-use 5-directional
joystick function. Using finger or thumb, you can
easily navigate the new T68i menu system. When
you arrive at the required function in a menu,
instead of pressing Yes, just gently press the
joystick and the feature is activated. The T68i
MMI is adapted for easy joystick navigation.
Bluetooth wireless technology
The T68i is among the first mobile phones on the
market with built-in Bluetooth wireless
technology. Using this reliable and secure
connection, the T68i can communicate with your
Bluetooth headsetormobilecomputerviaa
radio link instead of a cable, when the two
devices are within 10 metres of each other.
Unlike infrared, Bluetooth wireless technology is
not dependent on line-of-sight communication.
With a Bluetooth headset, wherever your phone
is when it rings, you can answer it. The phone
can be in your briefcase, your coat pocket or
even in another room.
Two or more mobile phones with Bluetooth
wireless technology can exchange data such as
images, business e-cards, ring signals, contacts,
notes and calendar data. It is also possible to
play interactive games between phones. You
could be at a meeting with your laptop open in
front of you and a new e-mail message is
displayed on the screen. In this case, your T68i,
which could be in your briefcase under the table,
has received an e-mail message and passed it
on to your laptop by way of a Bluetooth
connection.
GPRS
GPRS uses Internet-style packet based
technology. It lets you be permanently
connected to the mobile Internet, but only uses
the radio link for the duration of time that it
transfers data. GPRS offers the user the speed
needed for satisfactory mobile Internet usability.
The T68i supports GPRS 3+1.
More in-phone functions
E-mail
The T68i is one of the first mobile phones on the
market with a built-in fully functional e-mail
client. With inbox, outbox, save draft and reply
options, you have all the functions you need for
effective e-mail communication in a small and
powerful mobile phone. Constantly connected to
a POP3, SMPT or IMAP4 e-mail server anywhere
on the Internet, your T68i stores messages
(without attachments) dynamically, depending on
available memory, and updates your inbox
automatically and over the air. Check your e-mail
anywhere. Reply to e-mail on the move. Friends,
family and business contacts know that when
they send you e-mail, you receive it and can read
it and act on it immediately. You can include
pictures in outgoing e-mails, but not receive
attachments. Hyperlinks in e-mails are
supported.
Enhanced voice control
Lets you dial, answer, reject, change profiles and
usea“magicword”toactivatevoicecontrol.
Instead of having to press a sequence of keys to
activate voice control, you simply say a userdefined word or phrase and the voice control
function is automatically activated. You can also
redial a number by simply saying “redial”.
EMS (Enhanced Messaging Service)
You can send text, pictures and sounds in easyto-create and fun messages. EMS has been
adopted by several leading mobile phone
manufacturers, making it possible for T68i users
to send enhanced text messages to users of
other makes of mobile phones. EMS makes it
possible for the user to use text formatting (style,
size, alignment and paragraphs) in a text
message. At purchase there are several predefined images and animations in the T68i.
Predictive Text Input Software
Text messaging with your T68i is made easier
than ever with the introduction of predictive text
input software. Instead of having to press keys
several times for a letter, software in your T68i
chooses from a dictionary of words and phrases
and anticipates what word or phrase you are
writing, giving your mobile phone keyboard ease
of use comparable to that of a full-size keyboard.
Screen saver and sleep mode
The screen saver is activated when the phone
has been idle for 26 seconds. There is a pre-
T68i
White Paper, April 2002

defined screen saver at the purchase of the
phone, but the user can choose his/her own
image/animation as a screen saver. After a short
period of time the screen saver changes to sleep
mode, to save power.
Memory management
All applications in the T68i share the same
memory, allowing for efficient memory usage.
When the memory runs low, the user gets
information about the current memory situation,
where each application’s usage is displayed. In
the memory manager menu, the user can delete
items from any application, in order to set
memory free. The memory available for the user is
approximately 800 kBytes.
Notes (vNote)
With the Notes function, the user can make quick
notes that can be stored in the phone or sent to
others. One note can be displayed in standby as
areminder.vNotecanbesentviaBluetooth
wireless technology, infrared or MMS.
Mobile chat
Mobile chat makes text messaging easier, since a
chat-session opens up immediately when a text
message is received from a phone. Because the
user stays connected during the session, the
messages open up automatically. All previous
messages from both persons are visible on
screen, each writer being distinguished by a
nickname.
Picture phone book
The phone book in the T68i lets the user assign a
picture, a personal ring signal or a voice
command to a certain phone number. When the
user gets a call from this person, the picture
(instead of the number) is shown in the display. If
a personal ring signal or a voice command is
assigned to the phone number, that particular
sound is heard instead.
Calendar (vCalendar)
The T68i calendar supports week numbering and
lets you create, edit and delete both
appointments and tasks. It is a versatile mini
organizer. It stores appointment details, offers
day, week and month views and effectively
reminds you when something is due. Using the
advanced data capabilities built into the T68i, you
can also synchronize calendar, tasks and
contacts between your mobile or stationary PC or
other device and your mobile phone. vCalendar
entries can be sent via Bluetooth wireless
technology, infrared or MMS.
SyncML - for remote synchronization
SyncML is an open standard that allows you to
synchronize calendars, files and phone books
with any mobile device irrespective of model and
make. In the T68i, SyncML is used for remote
synchronization. This means that e-mails read on
the mobile phone, for example, automatically
show up as read e-mail messages on the desktop
computer. When the time for a meeting is being
changed at the office, the user gets the correct
update in the mobile, after having performed a
synchronization over WAP.
iMelody and Melody Composer
The audio iMelody format enhances the sound
quality in the T68i. With this format, the user can
play, compose, edit and send melodies within the
improved Melody Composer. The new composer
has an improved graphical user interface to
simplify melody handling. All new and edited
melodies are stored in the iMelody format.
Sound browser
From the Sound browser function, the user can
handle all sounds (for example eMelodies,
iMelodies and sound recordings) stored in the
phone. The user can play, edit, send and view
information on the sounds. Ring signals (eMelody,
iMelody, vMel) can be downloaded via WAP or
exchanged via SMS (iMelodies), infrared,
Bluetooth wireless technology and MMS
(iMelodies). Sound recordings can be exchanged
via infrared, Bluetooth and MMS. The maximum
number of sounds is limited only by the amount
of free memory.
Camera application
The camera application in the T68i supports the
Communicam MCA-20. The user can browse,
view, send and store pictures in the phone. It is
also possible to set different picture sizes.
Themes
With themes, the user can change the
appearance of the display, for example, the text,
the background colours and the background
picture. The phone comes with three pre-defined
pictures. It is possible to download and exchange
additional themes. The maximum number of
themes is limited only by the amount of free
memory.

Multimedia in the
T68i
The T68i is a multimedia phone. The colour
display together with the audio functionality
gives the user several multimedia possibilities.
Sounds can be recorded and pictures can be
created and edited. By using themes, it is easy to
change the appearance of the display. Pictures,
audio, animations and themes can be
transmitted via MMS.
Graphics
Graphics (tables, charts, diagrams and layouts)
has a major impact on the way we work. The
T68i supports JPG (max 640x480), GIF (max
160x120), WBMP (max 320x320) and animated
GIFs. With MMS, the user can personalize the
appearance of the display – for example the text,
the background colours and the background
picture.
Audio
TheuseroftheT68icanusethemobilephoneas
a sound recorder. With the sound recorder
function, it is easy to make a voice recording, for
example a personal rendition of “Happy
Birthday”. The audio function in the T68i also
allows downloading of sounds and melodies.
Pictures
With a digital camera attached to your T68i, you
can take, view and store pictures. It is also
possible to download colour pictures to your
T68i. The pictures are stored in the picture
browser in the phone. From here, the user can
select view, thumbnail or full view, as well as
keep track of the number and size of the pictures
stored in the phone.
The pictures stored in your T68i can be used for
creating your own digital postcards. This is easily
done by adding text to the pictures and sending
them via MMS.
Themes
With themes, the user can change the
appearance of the display, for example the text,
the background colours and the background
picture. The phone comes with a number of predefined pictures, and it is possible to download
additional themes. The maximum number of
themes is limited only by the amount of memory.

MMS (Multimedia
Messaging
Service)
One of the key features in the T68i is the
Multimedia Messaging Service (MMS), expected
to become the preferred messaging method of
mobile terminal users, since there are virtually no
limits to the content of an MMS transmission. An
MMS message from the T68i can contain text,
graphics, animations, images, audio clips and
ring melodies. For more detailed information, see
“Multimedia message service” on page 54. For
third-part developers’ information, please visit
www.ericsson.com/mobilityworld/ and look for
the MMS Developers’ guidelines.
Defined and specified by 3GPP as a standard for
third generation implementation, MMS completes
the potential of messaging. Sending digital
postcards and PowerPoint-style presentations is
expected to be among the most popular user
applications of MMS. Eagerly awaited by young
users in particular, MMS is projected to fuel the
growth of related market segments by as much
as forty percent.
Using the Wireless Application Protocol (WAP) as
bearer technology and powered by the highspeed transmission technologies EDGE, GPRS
and UMTS (W-CDMA), Multimedia Messaging
allows users to send and receive messages that
look like PowerPoint-style presentations. The
messages may include any combination of text,
graphics, photographic images, speech and
music clips . MMS will serve as the default mode
of messaging on all terminals, making total
content exchange second nature. From utility to
sheer fun, it offers benefits at every level and to
every kind of user.
MMS objects
Although MMS is a direct descendant of SMS,
the difference in content is dramatic. The size of
an average SMS message is about 140 bytes,
whilethemaximumsizeofanMMSmessageis
limitedonlybythememory.Thatiswhythekey
word to describe MMS content is rich. Complete
with words, sounds and images, MMS content is
endowed with the user’s ideas, feelings and
personality. An MMS message can contain one or
more of the following:
Te xt
As with SMS and EMS, an MMS message can
consist of normal text. The length of the text is
unlimited, and it is possible to format the text.
The main difference between an EMS and MMS
message is that in an MMS message, text can be
accompanied not only by simple pixel images or
melodies but by photographic images, graphics,
audio clips and in the future, video sequences.
Te mp la te s
The T68i comes with a number of MMS predefined templates, for example templates for
birthday cards, meeting requests etc.
Audio
MMS provides the ability to send and receive full
sound (iMelody and AMR) messages. Not only
can users share a favourite song ot ring signal
with a friend, they can also use the mobile phone
to record sound and send it along with a
message. Because sound includes speech as
well as music, this extra dimension of an MMS
message makes for enhanced immediacy of
expression and communication. Rather than
sending a downloaded birthday jingle in EMS, for

example, a user can send a clip of his or her own
personal rendition of “Happy Birthday”.
Pictures and themes
By using either a digital camera attached to the
T68i with a cable, or a snap-on camera
accessory, users can take a snapshot and
immediately send it to a recipient. The ability to
send pictures is one of the most exciting
attributes of MMS, as it allows users to share
meaningful moments with friends, family and
colleagues.
Mobile picture transmission also offers
inestimable utility in business applications, from
sending on-site pictures of a construction project
to capturing and storing an interesting design
concept for later review. Editing a picture by
adding text allows users to create their own
electronic postcards, an application that is
expected to substantially cut into the traditional
postcard-sending market.
Themes (downloaded or pre-defined) can be
exchanged via MMS.
SMIL presentations
SMIL stands for Synchronized Multimedia
Integration Language and is pronounced “smile”.
SMIL in the T68i allows the user to the create and
transmit PowerPoint-style presentations on the
mobile device. SMIL is an advanced XML-based
protocol, and Sony Ericsson MMS supports a
subset of this protocol. Using a simple media
editor, users can incorporate audio and animated
GIFs along with still images, animations and text
to assemble full multimedia presentations.

PIM communication with MMS
With MMS in the T68i, it is easy to send and
receive business cards, calendar entries and
notes.
Business card (vCard)
With MMS in the T68i, the user can send his/her
business card.
Calendar entry (vCal)
With the vCal function the user can enclose a
vCal entry when sending a meeting request via
MMS.
Notes
The T68i supports vNote. Notes can be sent via
MMS.
.
Benefits
Essentially enabling the mobile terminal to serve
as image processor and conveyor, Multimedia
Messaging accommodates the exchange of
important visual information as readily as it
facilitates fun. Business and leisure usage of
MMS will be dynamically merged, resulting in
enhanced personal efficiency for users and
increased network activity for operators. In short,
MMS affords total usage for total communication
Because MMS uses WAP as its bearer
technology and is being standardized by 3GPP, it
has wide industry support and offers full
interoperability, which is a major benefit to
service providers and end users. Ease-of-use
resulting from both the gradual steps of the
messaging evolution and the continuity of user
experience gained from interoperability is
assured.
The MMS server, through which MMS messages
are sent, supports flexible addressing (to both
normal phone numbers (MSISDN) and e-mail
accounts), which makes user interface more
friendly and allows greater control for operators.
The MMS server, moreover, is responsible for the
instant delivery feature of MMS.

MMS technical features
The MMS standard, just like SMS, offers storeand-forward transmission (instant delivery) of
messages, rather than a mailbox-type model.
MMS is a person-to-person communications
solution, meaning that the user gets the message
directly into the mobile. He or she doesn’t have to
call the server to get the message downloaded to
the mobile. Unlike SMS, the MMS standard uses
WAP as its bearer protocol. MMS will take
advantage of the high speed data transport
technologies EDGE and GPRS and support a
variety of image, video and audio formats to
facilitate a complete communication experience.
Architecture
The MMS Centre (MMS-C) is comprised of the
MMS Server, the MMS Proxy-Relay and the MMS
Store. The MMS Centre is the central element of
the MMS network architecture, providing storage
and operational support, enabling instant delivery
of multimedia messages from terminal-toterminal and terminal-to-e-mail, and supporting
flexible addressing. The centre’s MMS ProxyRelay interacts with the application being run on
the MMS-enabled terminal to provide various
messaging services. WAP is used as bearer of an
MMS message between the MMS-C and the
MMS client (application). The WAP Gateway is
used for delivery and retrieval of messages
Message conversion
The MMS-C is able to perform limited message
conversion - for example, from MMS to SMS - so
that processing and air time is not wasted in
sendingmessagestomobileterminalsthatdo
not have adequate capability to receive them. It
also handles service aspects such as store and
forward, guaranteed delivery, subscriber
preferences, operator constraints, and billing
information. The MMS-C also vouches for high
quality messaging, e.g. by format conversion.
This means that the MMS-C recognizes which
formats are supported in the mobile phone, and
adapts the MMS messages to these formats.
OTA configuration
Users can easily get MMS into their phone. MMS
supports OTA, meaning that the user does not
have to configure the settings manually. The
configuration is done by the operator.

EMS (Enhanced
Messaging
Service)
Enhanced Messaging Service (EMS) adds new
powerful functionality to the well-known SMS
standard. With it, mobile phone users can add
life to SMS text messaging in the form of
pictures, animations,sound and formatted
text.This gives the users new ways to express
feelings, moods and personality in SMS
messages. As well as messaging,users will enjoy
collecting and swapping pictures and ring
signals and other melodies, downloading them
from the Internet or editing them directly on the
phone.
EMS uses existing SMS infrastructure and
industry standards, keeping investments to a
minimum for operators and providing a familiar
user interface and compatibility with existing
phones and with other manufacturers.
EMS – more than just words
Sounds and melodies
EMS gives the user the ability to send and
receive sounds. These can be pre-defined
sounds, such as “Chime high” and “Notify ”, or
melodies (ring signals in the phone), downloaded
from the Internet, received in SMS messages or
composed by the user on the phone keypad or a
PC.
Several sounds and melodies can be inserted in
one message, and they can be combined with
pictures.
Pictures, animations and formatted
text
Phones supporting EMS include a set of predefined pictures for inserting in SMS messages.
New pictures and animations are downloaded
from the Internet or received in SMS messages.
Pictures can be created and edited in the phone
using a built-in Picture Editor. Several pictures
can be inserted in one message,and they can be
combined with sounds and melodies. The users
can format text in messages with different styles
and sizes.
Concatenated messages
ApartoftheEMSstandardisthesupportfor
concatenated messages, which means that the
phone is able to automatically combine several
messages both when creating and receiving
EMS. This is useful to be able to build,and
display,messages with rich content,since the
amount of information in each SMS is limited by
the SMS standards.
New possibilities with
messaging
The EMS standard is now a part of the SMS
standard and supported by the major network
operators and mobile phone manufacturers. This
universal approach enables a fast penetration
and development of new services and
applications within messaging.
Creativity explosion
Users will be inspired to create and swap their
own melodies and pictures. But more
importantly, professional content creators and
providers are already preparing to offer
imaginative and creative contents for use with
EMS. Based on subscriptions, fees or ads,
network operators will be able to provide wide
ranges of ring signals, operator logos and
corporate icons, as well as personal and moodrelated pictures and melodies. Movie, music and
game companies can promote new products and
events with designer melodies, animations and
pictures.
Huge business potential
Network operators can now enhance their
services and attract more customers by offering
pictures, animations, ring signals and melodies
for download at their portals. Operators can
charge more per EMS message since it contains
more data. Thereby EMS adds more value to the
operators and to the end users.
Increase SMS revenue
EMS uses the same basic network support as
ordinary SMS, and with the same familiar user
interface. From an operator's point of view, SMS
is low tech because minimal investment is
needed to provide an effective SMS service to
subscribers and little maintenance is required.
EMS will create additional revenue for service
providers and network operators by increasing
SMS traffic.
T68i

Compatible with SMS standards
Users will find EMS as easy to use as SMS. At the
moment 15 billion SMS messages, are sent every
month worldwide. Roughly 80% of this traffic is
user-to-user i.e. mobile phone users sending
short messages to each other using the keypad
of the phone to enter text. The remaining 20 % is
shared by downloads and notifications of
different kinds.
The Enhanced Messaging Service (EMS) was first
submitted to the standards committees by
Ericsson. Ericsson presented the outline structure
of EMS to the relevant ETSI/ 3GPP committees.
The major mobile phone manufacturers and most
operators are actively contributing to the 3GPP
standards. Hence the EMS standards have
evolved and are now stable and complete as part
of the 3rd Generation Partnership Project (3GPP)
technical specification.
An EMS message can be sent to a mobile phone
that does not support EMS, or only supports part
of EMS. All the EMS elements i.e. text formatting,
pictures, animations and sounds are located in
the message header. The EMS contents will be
ignored by a receiving phone that does not
support the standard. Only the text message will
be displayed to the receiver. This is true
consumer-friendly standardization. EMS is
compatible to SMS across most of the range of
mobile phones from the oldest to the newest.
Some companies in the mobile phone industry
have developed their own messaging
technologies, which only work with their own
phone models. Network operators are in favour of
EMS because it is universal – many of the major
mobile phone manufacturers are constructively
improving and developing the EMS standards
even further for implementation in their products.
Examples of EMS contents and
applications
A wide range of contents, applications and
services may be developed. Below is a list of
examples and areas where messaging can be
enhanced with EMS.
User-to-user message
Messages usually originating from the keypad of
a mobile phone can include pictures, melodies,
formatted text with EMS.
Voice and e-mail notifications
Notifying mobile phone users that they have new
voice or fax mail messages waiting - including
icons or melodies with EMS.
Unified messaging
The user typically receives a short message
notifying them that they have a new message in
their unified messaging box, with icons or
formatted text further enhancing the message.
Internet e-mail alerts
An Internet e-mail alert is provided in the form of
a short message that typically details the sender
of the email, the subject field and first few words
of the email message, and in this case formatted
text is excellent to identify mesage elements.
Ring signals
Downloading ring signals from the Internet
News & commercials
World news illustrated, sports scores and news
headlines, finance and stock market news with
diagrams and tickers, commercial product
promotions, weather reports with maps, tunes
from TV commercials as ring signals.
Info & entertainment
Ring signals, e-greetings, football club logo, jokeof-the-day illustrated by pictures or sound,
horoscopes, movie related animation or theme
song, TV show promotions, music artist
promotions, lottery results, food and drinks
pictures and recepies, mood-related pictures.
Corporate
Flight schedules, preinstalled corporate logos,
map snippets and travel info, company branded
icons and ring signals, corporate e-mail
notifications, affinity programmes where
companies notify customers of product updates
etc, banks notifying customers about new
services and interest rates, call centres providing
answers to questions about a product, vehicle
positioning combining EMS with Global
Positioning System (GPS) position information,
job dispatch with delivery addresses for sales or
courier package delivery, using EMS in a retail
environment for credit card authorization, remote
monitoring of machines for service and
maintenance purposes.
Using Web, WAP And SMS for download
Already today services exist on the Internet where
users can create melodies, and view icons and
pictures, subscribe to entertainment and
informations services. These may develop further
in the future to support access via PC over the
Internet, from the phone using WAP and even

with an SMS request interface.
The diagram shows a model over the possibilities with Enhanced Messaging Service:
- When the Operator/Service provider enables EMS in the network, users will enjoy adding life to
messages with sounds, melodies, pictures and formatted text.
- New ranges of Content/Application aggregators on the operator network or the Internet can provide
EMS contents and services to the users over SMS.
- Content Creators/providers can see a new demand for creative contents. Also, promotional activities
from movie companies, record labels etc can provide ring signals, movie snapshots etc.
The added value in SMS messaging will create new revenue which can be shared between the network
operators, the application aggregators and the content providers.

Bluetooth™
wireless
technology
The T68i features built-in Bluetooth wireless
technology. Its short-range radio link operates in
the globally available 2.4 GHz radio frequency
band, ensuring fast and secure communications
up to a range of 10 metres. Please note that in
countries where the use of Bluetooth wireless
technology is not allowed, the Bluetooth function
should be switched off. Contact a Sony Ericsson
representative to check if the use of Bluetooth
wireless technology is restricted in your country.
Bluetooth wireless technology is designed to be
fully functional, providing high transmission
speeds,eveninnoisyradiofrequency
environments. All data transfer is protected by
advanced error-correction methods, ensuring a
highlevelofdatasecurity.Formoreinformation,
see “Bluetooth technical data” on page 56.
Bluetooth wireless technology facilitates instant
connections, which are maintained even when
the devices are not within line of sight. Highquality voice transmission is provided under
adverse conditions, making it possible to use a
headset connection to the T68i at all times. A blue
LED (Light Emitting Diode) is used for the
indication of Bluetooth activity.
Ericsson is a founding partner of the Bluetooth
Special Interest Group (SIG). Bluetooth wireless
technology devices that are expected to be
available in the near future, include:
• Headsets for wireless voice transmission
and remote call control
• PCs,laptops,PDAs,palmpadsfordata

Synchronize
calendar and
phone book
In everyday life, access to an updated calendar
and addresses of friends and business
colleagues is greatly appreciated. To be truly
mobile, users must be able to carry their
important information with them. Equipping
mobile phones with Personal Information
Manager (PIM) programs such as calendars, todo lists and address books gives users access to
their most important data anywhere and anytime.
The information is kept updated by
synchronizing with the information at the office or
at home.
Hierarchical phone book with contacts
The T68i features a hierarchical phone book. For
every contact, details such as name, home, work
and mobile numbers, pager number, e-mail
address and other information can be stored.
The hierarchical phone book in the T68i is
compatible with most groupware and agenda
programs, such as Microsoft Outlook, enabling
smooth local synchronization of contact
information between the phone and a PC, via
cable, Bluetooth wireless technology or IR. For
remote synchronization of Contacts and
Calendar over WAP, the T68i supports SyncML.
SyncML,anopenstandard
for remote synchronization
in the T68i
SyncML – background
TheSyncMLInitiativeLtd.wasfoundedby
Ericsson, IBM, Lotus, Motorola, Matsushita,
Nokia, Palm Inc., Psion and Starfish Software in
February 2000. Supported by more than 600
software and hardware developers, the SyncML
Initiative Ltd. seeks to develop and promote a
globally open standard for remote
synchronization, called SyncML. Unlike many
other synchronization platforms, SyncML is an
open industry specification that offers universal
interoperability. Because it uses a common
language, called XML, for specifying the
messages that synchronize devices and
applications, SyncML has been called the only
truly future-proof platform for enabling reliable
and immediate update of data. The benefit for
the end user is that SyncML can be used almost
anywhere and in a wide variety of devices,
regardless of application or operating system.
For more detailed information, see “SyncML
technical data” on page 68, or go to
www.syncml.org.
What is SyncML?
SyncML is the common language for
synchronizing all devices and applications over
any network. SyncML leverages Extensible
Markup Language (XML), making SyncML a truly
future-proof platform. With SyncML any personal
information, such as e-mail, calendars, to-do
lists, contact information and other relevant data,
will be consistent, accessible and up to date, no
matter where the information is stored. For
example, a calendar entry made to a mobile
device on a business trip is equally available to a
secretary in a network calendar. SyncML is the
ultimate choice for remote synchronization.
In the T68i, SyncML supports remote
synchronization of the calendar and phone
bookDesigned for the requirements of the
wireless world
SyncML is designed specifically with the wireless
world’s tight requirements in mind. SyncML
minimizes the use of bandwith and can deal with
the special challenges of wireless
synchronization, such as relatively low
connection reliability and high network latency.
SyncML supports synchronization over WAP,
fixed networks, infrared, cable or Bluetooth
wireless technology.
In the T68i, SyncML enables synchronization
over WAP – an ultimate solution for travellers.

Benefits of a common synchronization
protocol
•Endusers
Today’s user of mobile devices probably
uses a different synchronization product
with every device. Each technology can
synchronize only a few applications, or is
limited to a particular type of network connection. This arrangement is expensive to
install, confusing to configure and operate,
and costly to administer. With SyncML,
userswillbeabletobuydevicesthatsynchronize with a broader range of data.
• Device manufacturers
Device manufacturers will benefit from a
common protocol that will make the device
interoperable with a broader range of applications, services, and network and transmission technologies.
• Service providers
Service providers moving into the growth
arena of application hosting are particularly
concerned that a proliferation of synchronization technologies will make it impossible
to deploy and support their customers in a
cost-effective manner. To support the
range of data types and devices in use
today, service providers must install and
configure multiple server infrastructures,
maintain and support that infrastructure,
and maintain compatibility and performance. The alternative now available, to
use a single solution for data connectivity,
involves the risk of a tight coupling to a
propriety solution. With SyncML, they will
be able to provide connectivity to a wider
selection of applications.
• Application developers
Choosing to support multiple synchronization technologies enables an application to
support more types of devices and networked data, but that choice comes at a
cost. With SyncML, application developers
will be able to develop an application that
can connect to a more diverse set of
devices and network data.

• Network operators
As multiple applications that need remote
synchronization over WAP are developed,
there will be an automatic growth of revenue for network operators.
Local synchronization
Open standard
Synchronization is possible with almost any
groupware or office program, since the
synchronization method complies with the open
standard IrMC 1.1, as specified by the Infrared
Data Association – reference http://
www.irda.org. IrMC 1.1 brings together the
following standards:
• vCard 2.1 for address book information
• vCalendar 1.0 for appointment and to-do
information
• ObEx (Object Exchange) for data
exchange
Bluetooth wireless technology or infrared
The T68i synchronizes using the same protocol,
regardless of connection type. It connects via
Bluetooth wireless technology, infrared or cable.
The cable is connected either directly to the
phone or to the desktop charger.
Automatic synchronization
When infrared or Bluetooth wireless technology
is switched on in the phone, the synchronization
process starts automatically, as soon as the
phoneiswithinrangeofacompatibleportona
PC or handheld device (a suitable
synchronization program must be running on the
device).
Intelligent process
A synchronization engine performs the task of
synchronizing. For local synchronization, the
synchronization engine is an application that
runs on the desktop computer. The
synchronization engine compares, updates and
resolves conflicts to ensure that the information
in the phone is the same as that in the computer.
Local synchronization software and
the T68i
PCs equipped with XTNDConnect PC For
Ericsson will perform synchronization with
Microsoft Outlook. For other groupware
environments (Lotus Notes, etc.), the full version
of XTNDConnect PC is required. By using
Bluetooth wireless technology, infrared or the RS
232 Cable, you can easily perform a fast, local
synchronization.
Integration between XTNDConnect PC For
Ericsson and Microsoft Outlook provides an
embedded menu for one-key synchronization.
To enhance functionality and compatibility
further, the synchronization software can easily
be upgraded.
The number of units that can talk to each other is
unlimited. One phone can be partner with several
PCs. This ensures that information from both the
work PC and the home PC can be synchronized
with the phone. For users that have both a
desktop PC and a laptop (free version
XTNDConnect PC) or a PDA (free version
XTNDConnect PC), it is an efficient way to
synchronize data with the phone. This way, data
can also be transferred between PCs to keep
them in sync.
If the synchronization software is upgraded to a
full version of XTNDConnect PC, one PC can be
partnered with several different phones. This is
vital if, for example, each member in a work
group has his/her own T68i, and needs to
synchronize with a PC. It makes it easy, for
example, to download a common company
phone directory to the phone book in each
company mobile phone. With the full version of
the synchronization software, other phone types
and handheld devices, such as PDAs and
Windows CE computers, can also be
synchronized.
XTNDConnect PC For Ericsson
This synchronization software can be
downloaded from
www.SonyEricssonMobile.com and provides a
powerful set of functions:
• T68i phone book and calendar synchronization with Microsoft Outlook.
• An embedded synchronization in
Microsoft Outlook, providing one-key synchronization and allowing the user to control the synchronization process with easyto-use settings.

WAP services
The T68i has a WAP browser, supporting WAP
2.0(WML1.3).WAP2.0 optimizesusageof
higher bandwidths and packet-based
connections of wireless networks.
The typical WAP client is a small, portable device
connected to a wireless network. This includes
mobile phones, pagers, smart phones, PDAs and
other small devices. Of course, compared to
desktop and laptop computers, these devices
are limited by user interface, low memory and
low computing power.
The WAP browser in the T68i is compliant with
WAP2.0andincludesWTLSclass3aswellas
mechanisms for digital signatures. It supports
WML and XHTML. The WAP browser in the T68i
is also designed to access information such as
timetables, share prices, exchange rates,
Internet banking and other interactive services.
For more details, see “WAP browser technical
data” on page 58.
Using WAP in the T68i
The built-in WAP browser in the T68i gives the
user portable, fast and secure access to a wide
variety of services, including personalized
services, with new opportunities for business,
individuals and service providers:
Push services
Businesses and service providers can “push”
content or service indications to work groups
and/or customers. Examples of pushed content
would be mail alerts, messaging, news, stock
quotes, contacts, meeting requests, etc.
Support of XHTML
The WAP browser supports the markup
languages of WAP 2.0 – XHTML Mobile and
XHTML Basic. These two subsets of the Web
standard XHTML are supported by all major Web
browsers. An XHTML page can be viewed in
both the WAP browser and in any standard Web
browser. All of the basic XHTML features are
supported, including text, images, links,
checkboxes, radio buttons, text areas, headings,
horizontal rules and lists.
Support for cookies
This version of WAP has support for cookies
(client based), an application used by Web sites
to store site-specific information in the browser
between visits to the site. Cookies give the site
owner a possibility to see when a person has
visited their site. They also save the user from
having to enter the same information (e.g. the
password or user ID) more than once. Cookies
are often used by e-commerce sites (shopping
carts and wish lists).
Sending bookmarks
WAP 2.0 enables the sending of bookmarks via
infrared and Bluetooth wireless technology (in
the vBookmark format) as well as via SMS.
Provide settings
Using SMS messages, configuration settings can
be sent over the air, OTA, so that the user does
not need to configure the WAP access settings
manually. WAP settings may also be customized
by the operator. For more information, see “WAP
Operator technical data” on page 59.
Adapt to phone type
The User Agent Profile function allows WAP
content to be automatically optimized for the
T68i, ensuring the intended user experience.
Several bearer types
The T68i accesses WAP over a standard GSM
Data connection as well as over a GPRS
connection (network-dependent services.)
Bandwidth efficiency
Unlike traditional Internet services, WAP services
are relayed to wireless devices as binary
encoded data, maximizing bandwidth efficiency.
A GPRS connection further increases efficiency.
Easy create for WAP
CreatingaWAPserviceisnoharderthan
creating an Internet/intranet service, as WML and
WMLScript are based on well-known Internet
languages such as HTML and JavaScript.
Using standard tools
Service creators can use standard tools such as
ASP (Active Server Page) or CGI (Common
Gateway Interface) to generate content
dynamically. Services can be created once and
then made accessible on a broad range of
wireless networks.
Maintain customer base
Existing services can be adapted to WAP. The
necessary binary encoding is handled by a WAP
Gateway, allowing HTML-based services to be

viewed on the WAP browser of the T68i. An
XHTML page can be viewed in both the WAP
browser and in any standard Web browser.
Improve productivity
A business can use a WAP gateway to provide a
secure connection to its corporate network,
improving internal communication flow by making
information available to mobile as well as office
users.
The WAP profiles
A WAP profile holds network settings and user
identification, allowing the user to switch easily
between corporate services and WAP services on
the Internet, simply by switching WAP profile.
The T68i has dynamic WAP profile handling,
which means that the user can add, edit and
delete WAP profiles. The T68i has a maximum of
5WAPprofiles.
During WAP browsing, the options button on the
T68i gives the user immediate access to a
dynamic option menu for WAP services, similar to
a mouse right-click in PC programs.
Bearer type characteristics
The T68i accesses WAP services over IP. IP can
be provided either over GSM Data or GPRS,
depending on network services.
Typical differences which distinguish the bearer
types are listed below.
GPRS access
• The connection is maintained “constantly”,
with data transmitted in packets, and
transmission capacity being used by the
application in use on an as-needed basis.
• Higher transmission speed than with GSM
Data or SMS access.
• Pricing of GPRS can be dependent on the
actual use of bandwidth, which means the
user is charged for the volume of data
transmitted, rather than the duration of the
connection.
• When transmitting large amounts of data,
bandwidth can be increased automatically
to allow faster transmission speed.
• Ideal for complex pull services, browsing,
data transfer, provisioning, pager services,
messaging services, info services, push ini-
tiations.
GSM data access
• Circuit connection of data calls, which
means that the phone is connected during
theentireWAPsession.
• Higher transmission speed than with SMS
access.
• Pricing is comparable to that of data calls
in the network.
• Suitable for complex pull services, browsing and data transfer.
• Not suitable for provisioning, pager services.
Gateway characteristics
A WAP Gateway provides Internet/intranet as well
as WAP services to the mobile browser. A
Gateway is identified by an IP number, depending
on access type.
End-to-end gateway navigation
The WAP 2.0 supports E2E (End-toEnd) Gateway
navigation, making it possible for example for a
bank to redirect its clients from the Internet
gateway to its own gateway.
Security using WAP
For certain WAP services, such as banking
services, a secure connection between the phone
and WAP gateway is necessary. An icon in the
display of the T68i indicates when a secure
connection is in use.
TheT68iisbasedontheWAP2.0(WML1.3)
specification suite, in which security functionality
is specified by a technology called Wireless
Transport Layer Security (WTLS). The WAP
protocols for handling connection, transport and
security are structured in layers, with security
handled by the WTLS layer, operating above the
transport protocol layer. WTLS classes define the
levels of security for a WTLS connection:
• WTLS class 1 – encryption with no authentication.
• WTLS class 2 – encryption with server
authentication.
• WTLS class 3 – encryption with both server
and client authentication.
