Tunewear has announced the Tunetag Edge, a dog-tag style silicone case for Apple’s iPod nano. The case, which covers only the sides and back of the nano, comes with a removable ball-bearing style chain so that you can attach it to a belt loop, bag strap or elsewhere. It uses the same high density silicone as the company’s Icewear cases, and allows full access to the headphone jack, hold switch and click wheel. The Tunetag Edge will be available next month. Pricing was not announced.
