Tunewear today announced Tunetag Edge, a dog-tag style silicone case for Apple’s iPod nano digital music players. The new case comes with a removable ball-bearing style chain so that users can attach their iPod nano to a belt loop or bag strap, and more. In addition, users can use their own strap (not included) to hang case around their neck. Tunetag Edge for iPod nano will be available later this month — pricing was not announced.
