XtremeMac has introduced a new TuffWrap silicone case designed to fit the latest version of the iPod nano, which has iPod dock and headphone ports in slightly different spots than its predecessor. Priced at US$29.95, the new iPod cases will ship Nov. 1 in smoke, clear, white, and black. The iPod case includes a detachable belt clip that rotates and secures excess earbud cords, as well as a universal iPod dock insert that allows the iPod nano to be used with accessories with the case on.
