AQUA TEK S is an innovative, versatile protective case designed for both iPhone 4 and iPhone 4S. As we can see from the images, the iPhone 4 case features a rugged, tough design, and is constructed from tough Poly-carbonate materials with rubber grips in order to protect the iPhone 4 or 4S from bumps and scratches, and provide you a solid grip, while its fully-protected structure allows you to take your iPhone to swim or underwater up to 20 feet. Moreover, the iPhone 4S case also features an integrated solar-powered charging system in order to offer your iPhone extra juice via solar panel and backup battery. Apart from that, except 30-pin port, the other buttons and functions of your iPhone 4 are accessible with ease.
