Well, I did some work with regards to streaming videos over GPRS a
while ago, and ahven in #openmoko was able to play a streaming video
that had a total bit rate of 52kbps with no lag. (H264 at 40 with
Vorbis audio at 12, and it looked and sounded better then the normal
YouTube mobile streaming too :) I'm pretty sure it can do more too.
There is info on the wiki about it, check out the GPRS class info.
