At the Nokia Mobile Internet Conference (NMIC), Nokia introduced six new phones (bringing the total for the year to 30!). The important thing for digital media developers is not the phones per se (although I really dig the 6800 pictured above), but that all support color and MMS.
MMS is Multimedia Messaging, which you’ll either consider an enormous enhancement of SMS (if you’ve ever taken a close look at what’s possible with SMS) or an eensy-weensy subset of the SMIL 2.0 specification (if you’re ever taken a close look at what’s possible with SMIL 2.0). It basically lets you send really simple image+audio presentations to phones and other extremely constrained devices.
MMS is defined as part of the 3GPP specification. TS 26.140 defines MMS and TS 26.234 (Section B and Appendix B) define the SMIL MMS profile.
