All of the ringtones listed on this page are being offered to you legally and at no charge. You have my permission to download them for your personal use. It is not OK however, to utilize them on a commercial level. Please feel free to contact me personally, via the email link on this site's main page, if you have interest in a commercial application. 

These ringtone formats should work just fine with most phones. I trimmed them to a length of 25-30 seconds and encoded them as 128 kbps mp3s.
