Or just get free ringtones from the cingular website

before going to the cingular website, clear out your temporary internet files, then head over to

http://www-xl.cingularextras.com/fuel/enduser/portal/endUserHTMLHome?pc=U&dc=0

Click the speaker icon to listen to the ringtones you want, they will then be stored in your temporary internet files in wma format. To get to them click tools>>internet options>>settings>>view files.

The ringtones will be called "content" with the little blue music icon. Now just drag them to where ever you store your ringtones on your computer. I use DBPowerAmp to convert them to mp3's, which takes all of 2 seconds, and they're good to go. 

Now they're only like 15 or 20 second ringtones, but they're free and easy, without having to hassle with ripping your own, they'll do in a pinch!
