This may be common knowledge/already posted, but- If you want free ringtones, and you have a Mac with Garageband, all you have to do is bring a song into a GB project (just click the media button and find the song you want). Once you have your song as a track, find the section you want and split the region so you have a section that is less than 30 seconds. Be sure to click the repeat button and drag the repeat bar so that it is equal to the section of the song that will be your ringtone. Click Share on the Menu Bar, select Send Ringtone to iTunes, and you're done. Free Ringtones, all-you-can-eat!
