My iPhone 4 is still pretty nice. I only put a bumper on it when I go to school or work, otherwise it's naked. My front glass is flawless as far as I can see, but my rear glass has picked up over 10 long (~1 inch) scratches in a month. Yes it's naked, but never touching any surfaces that should scratch glass, and it is never dragged on surfaces to create one-inch scratches. It's not something I would complain to Apple about, just wondering what you think about only ONE side of the phone scratching?
