Crackberry Guy writes "Research In Motion, the maker of the Blackberry, is looking into offering a wireless device that aims to thwart thieves and ease the minds of those who are prone to misplacing their handheld units. According to the recent patent application, the new device would be carried in a holster armed with a wireless transceiver. The handheld unit could be switched to a pickpocket mode so that once it's removed from the holster, a wireless alert message would be sent to the user. Unless a user authentication code is input in a predetermined length of time, the device's data would be rendered unusable."
