bluetooth passkey is an pairing passcode for your BlackBerry Bold. then you can pair your BlackBerry Bold with other bluetooth devices and transfer files via bluetooth. I had post howto pair BlackBerry Tour 9630 with Bluetooth headsets . it is the same for BlackBerry Bold 9000 and 9700. firstly turn on the bluetooth device you want to pair, then from your Blackberry bold Home screen, press the Menu key > select Manage Connections > select Set Up Bluetooth > Edit the device name, if desired > select OK > select Search > select a device > then enter the bluetooth passkey (The default passkey is four zeros (0000)) for the Bluetooth device > press the Touchpad. if you want to transfer files on your BlackBerry Bold via bluetooth, refer:How to send files from BlackBerry Curve 8520 via bluetooth
