Griffin Technology, as part of its new Co-Op Initiative, has announced a partnership with community-based online apparel store Threadless to produce a new line of accessories. First in the series are the new Clouds within the Thunder and Birds of a Feather cases for the iPhone 3G and iPhone 3GS. Each single-piece thin polycarbonate case offers a thickness of less than 1mm, and open access to all ports, controls, and the camera. In addition, like the t-shirt designs on which they are based, each case design is made in limited quantities. Both new Griffin+Threadless cases for the iPhone 3G and iPhone 3GS are available now and sell for $35.
