It’s amazing how a single grain of sand can supposedly destroy the glass back on the iPhone 4, shattering it into a million pieces. That’s not a burden that anyone wants to deal with, but you can prevent it with a simple $13 fix: install a metal back.
Yes, cell phone “modifications” can be a little intimidating for some folks, but apparently this fix is reasonably easy to do and it’ll only take a few minutes after purchasing a replacement metal backing plate. Basically, all you do is unscrew a couple screws, remove the glass backing, put in the metal replacement, screw it back in to place. Done. No more sleepless nights or worries of an abrupt sitdown breaking something.
The aftermarket metal back isn’t as shiny as the OEM glass one, but at least you don’t have to worry about it cracking. Even if it gets marred, you can replace it again for another thirteen bucks.

I’d like to know how all these transparent and metal backs address the issue of the wifi considering the metal spring next to the battery is supposed to make contact with the wifi antennae which is stuck to the back of the original. The transparent mod photos clearly show that spring contact nothing except plastic which would indicate the phone has a lousy signal after the mod!
