Protecting Against Bluetooth Discovery

If your BlackBerry supports Bluetooth, it is theoretically possible for other Bluetooth devices to connect to your BlackBerry. Once connected, that device can retrieve some of your stored nformation, including your contacts, e-mail messages, or calendar items.

If you are particularly paranoid — or even if you simply do not have any use for Bluetooth— you can easily turn off the Discoverable feature of your BlackBerry’s Bluetooth radio:

1. Go to the Options application and scroll to the Bluetooth option.
2. Click the trackwheel to display the menu and choose the Options menu item. You will see two fields: a Device Name (used to identify your BlackBerry to other Bluetooth devices) and a Discoverable setting (when turned on, enables your BlackBerry to be discovered by other Bluetooth devices).
3. Turn off the Discoverable setting by selecting it and changing the option to No.
