Carry your BlackBerry smartphone, cash and/or business cards all in the BlackBerry horizontal pouch. The pouch contains a card slot for your contents, and comes with a removable wrist lanyard. Grooves run along the inside of the case to protect the trackball. 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.
Warning: Do not place items containing magnetic strip components such as debit cards or credit cards in the pouch as it may erase data stored on the card.
