The BlackBerry® Leather Pocket is a form-fitted case designed to protect your BlackBerry Pearl¿ 8100 smart phone and its camera lens from bumps and scratches. It provides easy access to your smart phone thanks to a built-in thumb groove: just give your BlackBerry Pearl 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 smart phone into place. The sensor also allows you to switch automatically to different notification settings (for ringing, vibration or both) based on whether your smart phone is in or out of its case.
