Just when you though aluminum bumper cases dies a horrible death, Hornettek has taken a stab at this wonderful market of metal bumper cases with their version that they call the Vader. The Vader is an all-aluminum, two-piece bumper case compatible with both the AT&T and Verizon iPhone 4, and it will set you back $79.99. We've reviewed quite a few aluminum bumper cases on Gadgetmac before, and the Vader has some big shoes to fill. Will the Vader just be yet another run-of-the-mill aluminum bumper case for the iPhone 4, or will it prove worthy of your iPhone 4? Find out right after the break!
