The easiest & safest site would be
www.phonezoo.com... Register an account (FREE).... Pick a 'tone.... Have it sent directly to your phone... You receive a Multimedia Message... While listening to it.. press your options key.... Save as Ringtone......
Another really easy & safe place to get Ringtones is
www.zedge.comShould you decide to download Ringtones to your Computer instead of having them sent to your phone, we now do the following...
It's time to go to your favorite email account..
Address an email to ...
yournumber@vzwpix.com (area code included) attach the Ringtone of your choice to it and send...
Once it arrives to your phone (mere seconds in most cases) as the multimedia message plays..
Press your options key.. Save as Ringtone or Sound.. Reply to save as both.. Once saved as a Sound file.
You can now share this 'Tone by sending your friends a picture message with the 'Tone attached........ If you save the 'Tone just as a Ringtone, you will be able to use it as you would any other Ringtone already on your phone............
Please let me know how it works out..........
