popularity of mobile phone
messaging, Sony Ericsson has
incorporated the latest messaging
standard, along with a colour display for an
enhanced imaging experience.
Say it in words, say it with pictures, animate it, add
sound. Have fun putting together multimedia

stylized text, digital pictures of the location, and
authentic sound clips, to friends and family back
home. When shopping, send a picture of a bargain
that a friend has been looking for.
