what format does your ringtones have to be in? I know I have Hail to the Redskins in mp3, which works on my Verizon LG VX4500, and I know I downloaded it off the internet somewhere.

http://www.webskins.org/d.html#mus - wav version and mp3 version
http://www.redskins.com/fanzone/ - wav version
This should do it. If need be, you can find a converter online that will convert from wav or mp3 to whatever format you need for your phone.
