Accessory manufacturer Qmadix has hit the market with a set of three new iPhone 4/4S covers that vary in price and design but should appeal to a wide variety of iPhone owners. In this post, I'll take a quick look at the Qmadix Bezel Slide-On Cover (US$59.99), the Metalix Snap-On Cover ($29.99), and the Vibe Flex-Gel Cover ($24.99). Bezel Slide-On Cover As you might expect from the premium price on the Bezel Slide-On Cover, this lightweight and minimalist case is machined from aircraft-grade aluminum. It's similar in size and shape to Apple's original iPhone 4 bumper
