Since the Nokia Lumia 920 Windows Phone has only become available (and many customer orders are still backordered), the availability of accessories is still somewhat limited. Sure, you can pick up a few bigger name brand styles at the AT & T Store, but they’re awfully expensive. As such, many new Lumia 920 owners will be scrambling online to find a case to protect their phones. One affordable option is the S-Line Back Case from Cimo Technologies. Cimo produces the S-Line design for a number of phones and tablets, including the Lumia 920, HTC 8X, and HTC 8S Windows Phone 8 handsets.
