Hey guys, I keep my iPhone 4 semi-naked. It has super-clear glass protectors on the front and the back, the reason being that I want to keep the glass perfect for a possible resale in the future. The back protector also keeps the camera from touching flat surfaces when I place the phone down by raising it up a tiny bit. Anyway, I just thought I'd point out the different it makes when your phone has no oil-repellent coating. In my opinion, it's a small price to pay to keep the glass pristine, but I do have to clean the thing a lot more. Check out the attached images to see how greasy it gets after a couple of days of use! In case anyone asks, the photos were taken with a first-gen iPhone. Just kidding, it was done with my SLR and adjusted a little bit in Lightroom to bring out the detail.
