So I know that myself and many other people on here have had problems with the Apple Bumper not fitting snugly. There seems to be just a small amount of play. Here is a quick solution that will remove the play from the bumper, and all the parts other than the pair of scissors are provided by Apple. Instructions: 1. Find the white manual holder that came with your iPhone. It is made out out glossy white card stock paper. If your not willing to sacrifice that then find something that is the same thickness. 2. Cut a strip off that will fit the entire length of the right side of the bumper. 3. Put that strip into the bumper. 4. Apply the bumper to the iPhone and be happy. This fix should work for most people. If you intentionally try to make the bumper move it probably still will, however it shouldn't do it anymore while you are using the phone normally. You can always add more of the card stock to the other side to remove additional play if you need to. Hope that helps!
