IPhone TIPS: Metal back Replacing the iPhone 4 Glass back

If you are one of the people that is having "mental" problems with scratches on the glass back of your iPhone 4, you could replace your phone! No I am just joking :)  But if you are really, really afraid to scratch, break the glass back then there is a cheap solution. Warning: You may loose your apple warranty because you have to replace the glass back with a metal back. Cnet reports
" Removing the back--or "rear panel" as Apple calls it--is pretty simple (see ifixit.com's tutorial). And in just a few minutes you can swap in an inexpensive metal back for $12.99 from Hong Kong. Other backs are available, but Unpluggd says this is one of the few flat backs that's nicely beveled. (In the future, we expect to see many more backs hit the market)."
You can order this metal back at CNN.cn. Sounds familiar isn't it? Note: No I am not an affiliate.
Then got to ifixit to find the two screws.
I personally prefer my Bumper + Invisible shield Combo. Se Review HERE
