Key functions and features
Multimedia Messaging - Digital greetings
Reacting to the enormous popularity of mobile phone
messaging, Sony Ericsson has incorporated the latest
messaging standards into the T226 phone, along with a
color 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 your phone. 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.
With MMS, the subscription applications get more
interesting, for example stock information, movie
trailers and weather reports.
Polyphonic ring signals
Pleasing to the ear, polyphonic ring signals play
several tones simultaneously making a more musical
sound. The word “polyphony” means playing with
several tones at the same time. Almost all music that
we listen to consists of polyphonic melodies.
Polyphonic sounds and ring signals are finally
becoming widely used in GSM mobile phones.
The T226 will contain several polyphonic ring signals.
Users can share ring signals, and download them from
the Web.
Early Ericsson mobile phones supported a proprietary
non-polyphonic format called eMelody. Due to the
musical limitations of eMelody, and as it became
popular to create, send and download ring melodies,
Ericsson and Sony Ericsson, together with other
manufacturers created the more advanced non-
polyphonic sound format - iMelody.
The development from the iMelody format to the
MIDI format means a revolution to the sound quality.
The MIDI files are small, and perfect for mobile
devices which have limited storage capacity.
MIDI - Musical Instrument Digital Interface - is a
specification for a communications protocol
principally used to control electronic musical
instruments. MIDI is today a well known standard
used by musicians, composers, arrangers and so forth.
A MIDI signal or file does not contain any music, but
instead it contains binary data (information) of how a
melody is played. When these data reach a synthesizer,
the synthesizer will translate the binary data to music,
when connected to an amplifier with speakers so that
the sound becomes audible.

Downloadable games
Gaming is already a very popular feature in Sony
Ericsson phones. In addition to pre-installed games,
now the mobile Internet portal offers the possibility of
downloading games. Network operators may also
offer downloadable games to their customers as an
added value offer. Users can add new games and skill
levels to further enhance the entertainment value of
Sony Ericsson phones.
T226 downloading of games is made possible by a
true virtual machine. The Sony Ericsson portal for
downloading of free games is accessible via the WAP
browser. The openness of the downloadable games
solution is dedicated to provide an enhanced gaming
experience.
The downloadable games can fully take advantage of
the phone’s interfaces, such as TCP/IP, SMS, vibrator
and backlights. The virtual machine executes the
downloading of games for the optimal game
experience. The user can download an unlimited
number of games as long as the file system allows it,
i.e. until the phone memory is full.
The downloading concept includes certification of the
games, which makes it possible to create a revenue
chain and favorable business opportunities for
network operators and content providers. The virtual
machine uses true sandbox technology for highest
level of security. The software development kits are
available via www.mophun.com
