Hopefully this will not happen to mine, though I have to say the Apple store has not been a good experience for me. This weekend I had my speaker stop working and my receiver. I suspect it was the sensor in the phone jack, but anyway. I went to the Apple store, in the end the guy was said they cannot do exchanges since we are past 14 days, to which I very politely said, you are on crack if you think that a 23 day old device is going to be sent in for repairs. He told me that I could have a loaner, for 30$, while mine is in for repair.
Of course I again, asked if he was smoking crack (not my exact words). He went to see if the 30$ fee could be waved, when he returned he said it could. I told him that was fine as I was going on a trip for 2 weeks (which is true) and then he said that is a major problem for two reasons. The loaner is not allowed to be out that long, and when they try to deliver the phone to my home it will go back to Apple and there is no way to assure that if that happens I will ever get my phone back (that made me feel good.....). So the manager in the end, stressed that what she was about to do is not something they are allowed to do and should never expect this to occur again, she exchanged it for a new one.
So in the end I got a new phone, but was a royal pain in the a$$ for sure.
