Questions about copying music over to my 8310. Does anyone know how to convert/(use?) mp4s purchased on Itunes to mp3 for desktop and dragging to the usb connection. I've tried to without converting...just dragging and the phone registered receiving it but I can't seem to find it. I assumed that this phone doesn't support mp4s but I do see an Itunes folder icon set up ?? If it doesn't support mp4 why is it there?
