I doubt anyone else has had this problem, because the Apple Rep I talked to said that I was his first experience with this and that amazed me. In the midst of turning my iPhone to silent mode, my silver silent key decides to just pop off. 😱 So now I can't turn my phone on silent. I am driving THREE HOURS tomorrow just to get a new phone. I don't understand why there can not be an Apple Store closer, or why the AT&T Reps just won't do it.
