I had my red silicone case for about a month now, and today, when putting the iPhone in, one of the bottom corners just chipped. Guess it's because the case itself isn't silicone, but only the top layer. Because to me it feels like the case has a hard plastic frame which is covered in silicone. And it seems like this silicone layer can come off. Still i will have it replaced at the Apple Store tomorrow and hope it won't happen again. Anyone else has this happen to her/him?
