The OtterBox Commuter Series case for the BlackBerry Storm 2 9550 and 9520 series offers the best of both worlds; incorporating elements from the rugged Defender Series line with the silicone, skin-like Impact Series line to create a slick case designed with your style in mind. It's protection without the bulk. The exposed silicone corners dissipate impact away from the device for additional bump and shock protection and the smooth outer layer allows the case to easily slide into your pocket or purse. All buttons are fully functional through the case and the audio jack and USB port are accessible through silicone plugs.
