TUNEWEAR today introduced its new cases for some of Apple's third-generation ("3G") iPods, including the new 30GB and 40GB models. The company says it developed the cases for the previous generation iPod in order to accommodate requests from owners, but said it had no plans to produce sizes for the 10GB/15GB/20GB models, which are slightly thinner. The ICEWEAR series uses the same silicone found in diving masks which allows for both scratch protection and a clear view of the iPod's original design as well as access to all ports including the headphone jack, dock connector, hold switch and with Dock Connector. It also features shock absorbing ribs on the sides that also function as a grip for the iPod. Icewear 3G will be shipping at the beginning of December in limited quantities for $25.
