Bluetooth won't stay on

[hvykvy]

This is my first post so go easy on me.
I have an HTC Touch. I've had it for over 1 1/2 years now. Ever since I upgraded it to WM 6.1 I have had problems with bluetooth not staying on. When I first boot it up bluetooth will be on but goes off within a minute or so. After that it will not come on. I select it in comm manager and it goes through the motions but then stays off. I want to pair a headset with it but it won't stay on. I installed a hotfix from the htc site but no change.
Any ideas? I am in Canada on the Bell network. The phone has no sim card.
