I got my iPhone today from an ATT store, brand new, shrinkwrapped in the box. I started to use it and everythign seemed fine except that when I want to the App Store and tried to download a free app, it asked me to enter in a password. Ok, that's fine since I haven't tied my iPhone to iTunes on my computer yet, but there was a login already displayed which was an email address that I have never seen before. What gives?
