I dropped my IPHONE one time too many. Like toast it fell buttered side down. Broke the glass screen. The only thing that kept it from falling out on the ground and probably destroying the phone is the plastic screen protector I put over the face of the screen. You could see the cracks running all over the screen and the impact point but the phone still worked though it was hard to read. Cost me pretty to get the screen replaced.
Personally I will not go barefoot ever with my IPHONE. And I do not particularly want to test the IPAD either so will be putting on a screen protector. Just because.
