Since the release of the iPhone there has been a challenge to protect the phone while still maintaing the Apple integrity, we have seen super minimal cases that protect without drawing attention to themselves but the The iPhone 4/4S case MacPro takes the MacPro front and fits it to the back of your iPhone 4/4S.

The designer Cinemo recommends 3D Printing it in Polished White Strong & Flexible (Nylon) but it would look AWESOME in Polished Alumide too (though it may be a little fragile in this material)
