I repaired 2 iPhones this evening. The first one was an iPhone 3GS screen and the other an iPhone 4 front and back glass. The iPhone 3GS had been dropped by its owner and the 4 was driven over by its owner. I have repaired a few iPhone 4 that were driven over but I continue to be amaze how they seem survive every time. The newer iphone 5 would probably not make it as it is made out of aluminum. The glass back might be prone to brakage on the 4 and 4S but the 5’s aluminum back would bend and would have to be replaced.
Here are some before shots of the two phones.
