MaterialSix is now offering a complete line of wooden replacement back plates for the iPhone 4 and iPhone 4S. Built using OEM components—the back frame and camera lens—these handsome backs replace the original glass with a hand-crafted and -finished piece of wood. According to the company, installation of the replacement back requires the removal of only two screws from the bottom of the iPhone, and leaves the users’ existing plate completely intact, so that they may reinstall it later should they need to have the phone serviced, or if they simply tire of the wooden replacement. MaterialSix’ replacement backs for the iPhone 4 and iPhone 4S are available in a wide variety of woods for $89; special engraved “Art Series” backs run $99 each.
