M-Edge (http://www.medgestore.com/_ has launched the SuperShell for iPhone 4/4S. It’s designed to absorb shock and bounce when dropped. Available at medgestore.com, it costs US$29.99.
The SuperShell is made with”ultra-protective closed-cell foam.” Weighing just one ounce, it won’t add extra weight to your phone. The squishy foam material wraps around the edges of your iPhone for a secure fit, while the dimpled texture and ridges allow for a better grip, according to the folks at M-Edge.
