Blackberry Leather Pocket provides easy access to your smartphone: just give your BlackBerry Bold 9900 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.
