HOLY COW!!!!! My white iPhone 5 bent exactly the same way! It waws in an Otterbox Defender case for about 10-11 months (since new) and about 1 month ago the top button stopped working sometimes. So I took it to Apple get a replacement under warranty. When I took it out of the case I noticed it was bent. I thought I was going to be screwed with trying to get it warrantied. Nope! The "genius" noticed it right away too and said "it's a good thing you're getting a new phone today". I was so happy it didn't void the warranty. It made me like Apple even more that day.
