IvySkin has rolled out its new Quattro 4 case and SmartCase battery case for the iPhone 4. The Quattro 4 is a multi-layer case made from polycarbonate, polysilicon, enhanced TPE, and glass for the touch-thru screen. It features push-through protectors for the volume, sleep/wake, and Home buttons, open access to all ports, controls, and the camera, and a slide-off design for easy docking. The Quattro 4 is available now in a variety of colors and is priced at $45. Available for pre-order is the SmartCase for iPhone 4. Based on the Quattro 4, the SmartCase adds a 1500mAh onto the back of the case, with a USB port for charging and syncing, an integrated LED status indicator, on/off switch, and included back plate identical to that of the Quattro 4 for times when the battery isn’t needed. It sells for $80 and is expected to ship in the coming weeks.
