Just used this site to get myself free ringtones for my cell. If you have a cell that will play songs (lyrics & music) as a ring tone, you can use ANY mp3 file on your computer as your new ring. This also works if you have a phone that will play songs in "beep". Just do a search for midi files and download them on your computer (very small usually like 3-23kb). For this to work you have to have internet access on your phone.
