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 T310/T312 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 pre-defined themes, and it 
is possible to download additional themes. The 
maximum number of themes is limited only by the 
amount of memory.

Image formats
For information on Image formats and downloading 
of images, see “Image format technical data” on 
page 71 and “Images – downloading to phone” on 
page 71.

One of the key features in the T310/T312 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 T310/T312 can contain text, 
graphics, animations, images, audio clips and ring 
melodies. For more detailed information, see 
“Multimedia Messaging Service” on page 55. For 
third-part developers’ information, please visit 
www.SonyEricsson.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 high-speed 
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.
