iPhone 4 case by KarasKustoms is the simplest one we’ve ever seen.
Strictly speaking, we can call it iPhone 4 frame. Just as we see, the machined iPhone 4 case consists of two metal frames featuring anodized finish, which are put together with four screws. although the metal iPhone 4 case looks a bit simple, yet the metallic frame can prevent the iPhone 4 from some bumps. But for that uncovered back, you’d better apply an invisible shield on it.
