Grantwood Technology today announced the release of the tuneband for iPod nano (US$14.99), an armband product designed to comfortably secure the iPod nano in place during exercise, including Nike+iPod compatibility. Each tuneband consists of a comfortable and flexible armband strap that can accommodate both large and small arms, a durable silicone skin that allows access to all ports on the iPod nano, and a low-tack, cut-and-peel screen protector that helps guard against smudges, moisture, and daily wear-and-tear. The tuneband is fully compatible with the Nike+iPod Sport Kit, allowing runners and walkers to enjoy this workout companion.
