The BlackBerry Leather Pocket is a form-fitted case designed to protect your BlackBerry Pearl 8100 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 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 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. To differentiate from BlackBerry Swivel Holsters please note that this pocket does not have a belt clip.
