Most of them have no picture and just have sound.
90% of those that do play have the sound 10seconds in front of the picture.
Anything over 240×320 or 320×240 wont play on the phone, and they obviously cant be a zip file or rar file as the phone wont extract passworded files.
70mb unpassworded files take 4hours to extract.
I cant download from a personal because i dont have one any more, it smegged up on me!
