Audio

With the sound recorder function in the T610/612, it is easy to make a voice recording, for example a personal rendition of “Happy Birthday”. The audio function in the T610/612 also allows downloading of sounds and melodies.

Themes

With themes, the user can change the appearance of the display, for example the background colours and the background picture. The phone comes with a number of pre-defined 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 T610/612 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 T610/612 can contain text, pictures, graphics, animations, images, audio clips and ring melodies. For more detailed information, see “Multimedia messaging service”.

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.

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, while the maximum size of an MMS message is limited only by the memory. That is why the key 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:

Text

As with SMS and EMS, an MMS message can consist of normal text. The text can consist of up to 1000 characters. 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.
