This is not to discourage you, though. I bough my case online and any clear case will do. I purchased a Speck case, because I am a klutz and I hoped that it would protect the best (It's held up so far!) but you can get much cheaper cases on Amazon (disclaimer: I have no idea if these work or last as long).

Step 3: Use the back of your phone to carefully trace the outline of your phone onto the thing that you want to become your phone decal. Cut it out.
Step 4: Use your phone case to trace the outline of the camera hole onto the phone decal. Cut out.
Step 5: Put this into the back of the case and then stick your phone in. Voila! Look at you, Martha Stewart (MStew?). No more plain old phone cases.
