The genuine BlackBerry Pocket is a form-fitted case designed to protect your BlackBerry Curve 8900 smartphone and its camera lens from bumps and scratches. It provides easy access to your smartphone thanks to a built-in thumb groove: just give your BlackBerry Curve a gentle tug and it slides out smoothly. Plus, it features a battery-saving proximity sensor that shuts off the screen backlight as soon as you slide your smartphone into place. The sensor also allows you to switch automatically to different notification settings (for ringing, vibration or both) based on whether your smartphone is in or out of its case.
