Not sure this will help ...but worth a shot
Enabling trust mode prevents your BlackBerry device from disconnecting from your Bluetooth device after each call.
From the BlackBerry main menu, select Options > Bluetooth.
The Paired Device screen appears.
Scroll to your Bluetooth device and click the trackwheel.
Select Device Properties.
Set the Trusted field toYes.
If that does not work maybe try removing your battery for a few and seeing if that helps you. Bryan Kuhn
