Ringback tones don't "Show Up" on your phone. They are only heard or used when someone calls you. That's what they hear instead of a 'ring' on the phone. I have had them for two years, and on my Droid since I got it in November.... Everytime someone calls me they hear one of three 'James Brown' Classics! There is nothing on my phone to indicate I have them, I manage or change them over the internet.
