I've used a bumper on my 4S since it was released (in combination with front and back films), and while I love the unintrusive design, I'm left with a phone with a severely scratched steel band. See the photo below. I'm ready to upgrade to the 5s, and I'm looking at bumpers, but I'm afraid the same issue might reoccur. Obviously, I could be diligent about cleaning the bumper often, but I'd love to know if the iPhone 5 design has been any better about withstanding scuffs and scratches against bumpers. PS. Enjoy my wonderful hand modeling.
