The BlackBerry Leather Pocket is a form-fitted case designed to protect your BlackBerry smartphone from bumps and scratches. It also provides easy access thanks to a built-in thumb groove: just give your BlackBerry a gentle tug and it slides out smoothly. Plus, a magnetic proximity sensor determines if your BlackBerry smartphone is in its case and shuts off the screen to conserve battery life, while giving you the option to choose unique notification settings for incoming calls and other functions.
