Depends on the BlackBerry model, its software and the Bluetooth module software in your LR3. For instance, a BlackBerry Storm (Verizon) of one of our salespoeple won't pair automatically to my "old" MY06 RRS: Every time the phone detects Land Rover it requests the 2121 pairing code before reestablishing the Bluetooth connection. But my own BB Pearl - also by Verizon - has been working like a charm for years with the car. The same Storm handset pairs automatically and works great - including the phonebook download over BT feature - if you have a MY08 LR3, or an earlier model year with upgraded Bluetooth module.
