I think amd4me is talking about wiping the EPST info (or whatever its called), that holds all the activation information. When your friend gave it to you, did you activate your own number on it or are you still using his old phone number?

It seems that Pandora associates your phone number or something else out of the EPST to your account because I've never had to re-enter my login information after a hard reset. The only time I've had to re-enter log in information was when changing phones.
