DoCoMo changed i-motion file format from ASF to MP4 for the new
handsets, good they are learning from the rivals, bad the content
providers have to change their software and reproduce video files.

au/KDDI's ezmovie has been using MP4 for sometime, but a different
voice coding.  DoCoMo uses AMR, while au uses QCELP or MP3.
don't know if we will see UMTS and cdma2000 operators agree on
a common voice format, SBR maybe?

... btw, what's 3G-324M for?
