The iPhone has gone through many changes since it first came out, changing from an aluminum backing, to a plastic backing, and then it has finally ended up with glass backing. For many people though it may be not to difficult for them to choose which they like most, but if you are still on the border of the aluminum look or the class backing, it can be easily fixed with a sticker. This $10 will get you back into the aluminum look and when you get tired of that you can simply take it off and go back the glass design whenever you feel like it. It may be a good idea, but I think that the glass backing looks much more elegant and I wouldn’t want to pay money for my iPhone 4 to look like the original iPhone.
