Build your own ringtones

[The Brez Man]

I used Ringbuilder ($.99) and got it when it was free. You can take any snippet from any song you have on your iPhone and create a ringtone. Then connect your phone back up to iTunes and transfer it to iTunes. Then you have to drag it into your ringtones area on itunes and drag it back to your phone. It's a pain that Apple won't allow these apps to save that info directly to where it needs to be in the phone, but it's better to do it this way than the old way I used to do it (all on the computer, changing import properties, etc.)
