Frankly I am suprised the cracked screen percentage went up so little from a 3GS. I have had everyone of the iPhones and the iPhone 4 is the only one that I have a crack on. I had dropped it on concrete in the parking lot from about 2 feet. Thankfully it was only a small crack on the back side of the glass. Still, I could not believe how easily this was damaged and I hope this 'feature' changes on future models.
Same here, the 4 is the only one I've cracked and I've dropped them all. Dangit
