I was rushing out of my house today. Opened the door. Saw it was raining. Went to transfer my iPhone from my back pocket to my hand so that I didn't sit on it when I rushed into the car. Managed to drop it on the ROUGH concrete and put a nice scratch/dent in the corner. Works fine. Can only be seen from the back but bothers me. Anyone know how much the Apple Store will charge for a new back?
