I am able to use an MP3 as my default ringtone; but, when I set them for individual contacts, only the default ringtone plays. Can anyone help me with what I am doing wrong? Thanks!
I dont do this from the people widget. I usually use Zedge ringtones to find ringtones or RingDroid to trim MP3s to a shorter length. Both allow you to assign to a contact, and I've never had a problem with either. Market links below.
Another option is to open the Music app, scroll to the song you want and then tap menu -> more -> set as ringtone -> contact ringtone. I've never had any problems doing it this way.
