Hello...just got my Blackberry HS-655+ Bluetooth Headset today! Loving it so far! My question is this: Is there an option somewhere that will turn off the bluetooth antenna on my BB whenever I turn off my bluetooth headset? I have a friend who's phone will do that for him, except it's not a BB...suggestions?

AFAIK, there is no way to do this automatically when you power down your headset. It can be done manually via the Manage Connections icon on your homescreen.

On my curve 8310, is there a way to boost bluetooth signal strength?

I assume this means he has to turn it back on to connect to bluetooth again. So your would only be getting 50% benefit from turning yours off manually.
