Yesterday the case on my iphone randomly cracked. I didn't drop it or do anything to cause it to crack. I called Apple and without any questions they are going to send me a replacement. I have a feeling that the crack was caused by using the iPhone dock. AppleCare rocks. Sure you could say that maybe the back of my iPhone shouldn't have cracked, but things do break. The fact that I could call up some guy, email him a photo of the crack, and with in 15 minutes it's processed for me to get a new (probably refurb) iPhone is pretty great.
