I can't complete the process since my 9930 and pb are already paired. But open the Bridge app on the phone. There should be selection "Add New Tablet" highlight and Select that. You then get a screen that has instructions - generally Run BB Bridge setup on the Playbook and get the pairing barcode. 2: Click continue on the phone and Scan the pb's displayed barcode. Or Do manual pairing.
Okay, I thought it was clear.
This BRIDGE function is different from setting up Tethering. That I can't help with as I have not done that. But Bridge is a very similar process and allows the pb to use data from the phone.
