I purchased my iPhone. I have the reception issue, but don't really care. A case solves that. But I took it out of the case to show to a friend on Friday, and placed it on my desk. The back of it had a crack on the bottom left hand corner when I picked it up! I definitely set it down carefully, but it just cracked! It's a single hairline crack on the bottom corner. I'm kind of shocked to be honest. Will Apple replace it? I most definitely did not drop it, and there are no signs I did. There's just a crack there.
