Tunewear today announced the Icewear 4G, a transparent silicone case for Apple’s fourth-generation iPod. The IceWear 4G uses the same silicone found in diving masks, and allows access to all ports including the headphone jack, dock connector, hold switch and click wheel. Shock absorbing ribs on the sides not only serve to protect the iPod during falls, but they also function as a grip for the iPod when held in your hand or when placed on most any surface, according to the company. The Icewear 4G is priced at US$24.95.
