So last January (2012) I got a white iPhone 4S 16GB from Verizon and I also ordered an otterbox defender case for it. Well, I've had it in that otterbox ever since the 3rd day of owning it (the otterbox arrived late), and I've never taken it out. I'm not one of those immature people who constantly change cases/take the case off their iPhone. Well today I took it out, because my otterbox is falling apart & I got a new case. Somehow there's a crack on the back of my iPhone, where it says "iPhone." How did it get there? This iPhone has rarely ever been dropped and when it has been dropped it was never high enough to break it through an otterbox defender case. Foes anyone have a clue how it got there because I'm a bit pissed.
