I have a black 32g Verizon iPhone 5 and my girlfriend has a white 16g Verizon iPhone 5. They came out of the box without noticeable flaws however, our power buttons rattle. Her case puts slight pressure on the bottom so it isn't a problem for her. For me, when I have the phone on vibrate, it sounds like a dentist drill due to the rattling. I can wobble the phone and hear it. I can replicate the sound by moving the button with my finger. I plan to exchange both phones. Anyone try exchanging yet? How has the experience been given that the phones are still out of stock? Anyone else experiencing this? When the Verizon iPhone came out, my black 16g did not do this but my friends black 16g did. Please help! The vibration setting is pointless because my entire office can hear the thing.
