so a buddy put me under his Dev account so I could legally install the 3.0 beta. Is this legit with apple? I can't seem to get an answer. Today i went to the apple store for some help with my iPhone since the battery is going to crap and he said that I would have to log into my DEV account and verify I am aloud to have 3.0 in order to replace the phone? Does anyone have a definite answer?
