I am popping back to the Apple genius bar tomorrow to receive my replacement iPhone 4S. I would (and should) be looking forward to it (as I am getting it to fix the greyed out wifi toggle) but I am not. I am nervous that they will discover that I am on iOS 6.1 beta 4 (not a developer, UDID registration) and refuse me a replace. The man I saw yesterday at the genius bar immediately told me that it was a hardware issue and hit that juicy 'Repair' button on his iDevice. I was very lucky to get such a nice guy on that day and was hoping to walk away with a new iPhone just like that, but he recommended that I take it back home and back it up. What should I say if they say, "How come you have iOS 6.1 beta 4!"? I am also with my mother that kills me (not literally) on the first signs of any mess up. HELP?!
