I like to go naked. Well, I should say, I LIKED to go naked. It looked so sleek and sexy naked, no case, just a slim piece of phone. Not only that, when you set it down just right on a very flat surface you almost got a bernoulli effect and the phone would just hover in true Apple fashion on a cushion of air for just a moment. It was great, until the circular lens of my camera got scratched, then more scratched and the great camera became worse than the old flip phone cameras. Everything was fuzzy and cloudy.
It was amazingly easy. Two screws out, cover off, new cover on, and a quick test to make sure it still hovered over the surface like it should, then quickly added a clear back case to make sure this didn't happen again. Pictures are crisp, clean, clear, and back to their great quality, and now I can see the attention to detail Apple spends on even the parts the customer is never supposed to see.
Looked at the el-cheapo models from other retailers, lots of complaints on quality. This is great, good quality clear glass, metal screw brackets, snug fit but not too snug. Spend the extra for quality, customer service, and great company that shows you how to DIY.
