I don't want a film over my screen. I haven't had problems with any of my iPhones' screens scratching (though the oleophobic coating on the iPhone 3GS has scratches that you can only see in very specific lighting). A film takes away from the quality of the screen. It seems like the back of the iPhone 4 may be more scratch-prone than the screen. What is the best film to have on the back? Which feels the best resting against your palm for hours every day, which is scratch-resistant, etc.? I'd buy a kit with a film for the screen and back, though I would not put anything on the front of my iPhone 4.
