I have an SPH-A640 from Sprint, and am trying to figure out how to copy mp3s to it. I have tried bluetooth, trying to copy from a Moto Razr, and it keeps saying "invalid file format" when I try to copy. It does this for every file, jpg, mp3, etc. Is there anyway to copy ringtones to this phone? I have even tried with a data cable.
Thanks.
