well here's how it breaks down for me, 1 size; Sprint Official=834k,
no .gif support and a much cheaper interface
sMMS=372k, no video, but a much more friendly interface.

all in all I think ill stick with sMMS just for ease of use! on a side note if one guy with a little knowledge and a desire to make something work cas come up with a program like sMMS, why can't Sprint pull there heads out long enough to get it right? or at least a lot closer.
