maybe you suffer under this: bridge is not connecting with Playbook
in the BT settings of the PB, delete the Blackberry phone,
in the Bridge settings of the BB, delete the PB
make a battery pull on the Blackberry
Again mate the PB and the BB with the pairing assistant of the PB.
works for me, everytime I am hit with this bug. sometimes it takes days, even a week until this happens, but then it can occur even one time a day.
