Finally we get our hands on Pinlo's newest creation, the United bumper. It's a two-piece hybrid type of aluminum bumper case for the Verizion and AT&T iPhone 4 that doesn't use any screws and tools to get it on your iPhone 4. Simple yet very interesting looking. The United take on Pinlo's way of making very slim and thin iPhone 4 cases and it's the slimmest and lightest hybrid aluminum iPhone 4 bumper case I've ever tried. A hybrid aluminum bumper means one thing, better reception. Is that the case with the United? Find out in the full review right after the cut.
