My friend dropped his beautiful wife on the concrete today. Here is the aftermath. No scratches at all on the front glass or the rear glass. It slipped out of his leg (while the iPhone 4 was sitting on top of his legs) when he exited his car. His iPhone was naked (aka no case whatsoever) It tumbled onto the concrete ground and bounced several times cracking the edges of the front glass and nicks and scrapes around all edges. UPDATE: I thought it chipped the glass, but here are the updated pics - it did not chip any of the glass parts!! It actually only crushed the RUBBER GASKET AROUND THE GLASS. No other visible damages - even the stainless steel had a few small tiny nicks. I saw his phone today so I can confirm and here are the large pics: i guess the front and back glass of the iPhone 4 really is scratch proof! The edges and sides, eh....not so much!
