Last week I dropped my phone down the escalator on the underground and it must of travelled about 100m bouncing along.
The screen saver was shattered and fearing the worse I thought the iPhone screen could not survive that treatment.
Removed the screensaver to find not one single scratch or crack on the iPhone screen!
Have now purchased another as the screen replacements are £100 plus the time without a phone -worth the money!
Would highly recommend
