Many offers online for "complimentary" ringtones but I have had no luck finding any that support US Cellular. The other thing I have found is you must complete 6 surveys or pay $9.99 - I am looking for TRUE FREE RINGTONES - Anyone so lucky???

Yes, I did.
They are at http://www.funformobile.com

Be careful! Most ringtones offered anywhere are a scam! Never listen to stupid ads you see on TV (like MTV) that say "Text RAP3 to 23423 for a free (insert rapper here) ringtone! Oh yeah!"

Those services sign you up for about a $30/month crap service of sending you unwanted tones and stuff.

That out of the way go to howardforums.com and sign up. You can learn how to make your own ringtones from MP3s you already have and send them to your phone with a USB cable. Depending on your phone the USB cable can cost you anything from nothing if you already have it (your digital camera's cable works on a Moto RAZR for example) to about $25 on ebay. Ask on the forums there and you'll discover a whole world of free goodness.

Good luck!
