Tashanna sent me a link to a great website full of free ringtones. It also lets you create your own ringtones from an MP3 file or URL. The coolest part is that you can even enter in a YouTube URL and it will create a ringtone out of the audio from the video. It then lets you cut up the audio file into the segment that you want.
There is quite a range of free ringtones available and so far I have not found any that require payment. You just download them directly from the site to your PC. I tried it from my BlackBerry but that sadly did not work. They supposedly have a mobile version of the site in the works.
Check it out at www.audiko.net and let me know what you think. If you know of any other good resources let us know!
