Protect your precious iPhone without having to cover it with a case using the iPhone 4 Metal Back. This metal covering replaces your iPhone 4's fragile glass back screen with a tough-as-nails metal piece.

The iPhone 4 Metal Back isn't a cover, but is a piece actually made to screw into your iPhone. Simply unscrew the glass back and install the beveled metal one in its place. Your phone will look instantly cooler with its new-found industrial look and it will be less prone to damage when dropped. Sounds like a win-win to me.
