The iPhone 4 is a good looking device, but it has glass on both sides, seriously? Not sure if Steve Jobs really likes glass or hopes for the break/upgrade program. Either way, until recently, your only option to toughen up your phone was to strap on a case or bumper.
Enter the new iPhone 4 metal back plate which replaces the glass iPhone 4 backing. The metal backing even has the Apple logo and standard text. Simply spend about $13, remove a couple of screws, and tada you have a unique iPhone 4 without a case.
It is no secret that Steve Jobs is not a fan of covering his beautiful Apple products with cases and the like, so I am not sure how long this (most likely not authorized product) will last before his legal team is all over it.
