I went into the ATT store earlier today to upgrade a phone to our account. (Not mine yet though, had to go through radio shack and will have mine next week.) Next to us was a gentleman that had gotten an iPhone 4 that morning, I'm guessing at the store at that time, cause he still had the iPhone 4 box and his 3GS with him. He had some kind of hardware problem and now has to send in his 4 to Apple. I felt sorry for him but happy for him at the same time. He will for sure be getting a new one, because refurbs are not in the supply yet, but I felt sorry for him because he couldn't even use his phone on the first day and will probably have to wait a week before he can have a new 4 back to use it. The ATT rep had to reactivate his 3GS for him to use in the meantime. I told him good luck and hopes that he gets it replaced quickly. Sucks doesn't it?
