I basically have found that all these "shields" is nothing more than the biggest money making scam thats made off all smartphones to date. I found that the shield is more prone to scratch than the screen will ever be (its plastic), as I was buying new batches every other month I always thought to myself, 'whew good thing I had a shield on it otherwise that would have been a scratch on my screen' and off I went to spend more money needlessly. That was with my 3G after I wised up and seen the light, I stop using them and when I got the ip4 nothing went on it, well my naked 4 never got a single any scratch front or back and I still have the 3g since release, guess what, yeah besides a superfine 4mm hairline scratch only seen in a glare theirs nothing...I choose not to believe the hype and put that money toward something more useful..
