I recently bought a Jawbone 2 headset. The fit and sound quality can't be beat, but it's driving me up the wall because it turns itself off 15 minutes after the phone goes to sleep.

Is there any way to configure the Bluetooth stack so that it remains powered on and connected to the headset even when the phone is asleep? Ideally I would like to set it up in such a way that pressing the voice dial button on the headset wakes the phone up and starts MS Voice Command.

I'm using the latest 5.0 firmware from UTStarcom; I haven't upgraded to 6.1.

Well, some registry searching, followed by Google, led to this:

Problem solved.
