I purchased the Power Support Anti-Glare Film from the online Apple Store and it just arrived in the mail. Putting it on the front is easier, because you can just line it up with the home button. The back part came out uneven at first, but since it sticks to the static, instead of adhesive, I pulled it off easily with some Scotch Tape, like the directions explain, and repositioned it. Air bubbles were present, but I massaged them out. They also have clear film, but the anti-glare makes watching videos awesome.
