How large of a file can a picture, video, or audio be when being sent as a MMS?? is there a way to send an audio file(song on ipod app) through MMS? EDIT: In Settings.app>General>Network>Cellular Data Network> Scroll down to MMS Max Message Size... mine says "614400". But 614400 what? KB? I can edit the file number... if I edit it to a larger number, does this mean I can send better quality stuff then???
