OK, my 13 year old son found this site and when I am not on here I am on this site making ringtones from mp3's on my computer. You can browse through thousands of ringtones as well. These can be used with almost any cell provider. I know I have verizon and it works for me. My friend has T-Mobile and as long as she has her internet browser service on her phone it works for her. All you do is sign up and browse ringtones or upload your own mp3 and pick any 20 second increment of the song you want. Feel free to add me with this screen name to your friends list and browse through my tones.
