Hello,
Is there a limit to the size of an mp3 file one can send to ones phone to use as a ringtone? i mean other than the obvious memory limitation of the phone itself.
The .mp3 needs to be 30 seconds or less, and I have had issues if the bitrate was set too high (that was an older phone though). Use Audacity (a free audio editing program for your computer) or Phonezoo (a free online ringtone editing service) to get just the clip you want.
HTH,
