I'm new to the forum, and I apologize if this method has been posted before, but I think it is a pretty cool way to create ringtones for the iphone.
If you don't have the mp3 of a song you like, search youtube for the music video. Then, open up garage band, and delete the grand piano track. Then, select new track, choose real instrument track. Then, make sure that you are in a quiet room, start the video, and press record in garage band. Close youtube, edit the song to the proper length, and export the ringtone to iTunes.
Sync your phone, and enjoy the new tone.
