Named for its wave-shaped closure, the Griffin Wave case for the iPhone 3G is made of polycarbonate material and features a touchscreen protector that allows you to still have complete control of the touch display. You also get full access to all the external controls and ports. The Griffin Wave for iPhone 3G is available in five colors--black, white, blue, green, or pink--and costs $24.99 each or $34.99 for a two-pack.
