Only thing on our two iPhone 4's are the back plastic from the factory. Tab cut off from the bottom and the corner cut out around the camera. Nothing else on the phone. No issues.
I purposely dropped my phone from 1 foot up on a rug over hard wood. Nothing. I did a 2 foot test drop. Again, nothing. I moved it up to 4 feet. Nada. So, dropping it on a 1/2 thick rug on hardwood (no padding) results in - YOU GUESSED IT - no damage
