This is from Tech guy on like page 11 of these threads
Simply open up the Hp wireless window ( do not click on the toggle icons but on the bar itself to open up the dual tab window, if were talking about the same problem, the BT tab will not be available ).
The trick is to close the hp wireless app using a task manager ( not the X at the top even if its set to close )
I personally use quickmenu, once the proccess is killed the today plugin still shows but the x on each toggle icon will be replaced by a gray one. Simply tap this bar and the hp wireless tool will reload properly and will be able to manage both wifi and bt.
It take me only 3-5 seconds to do so it is a very quick and simple fix for me.
So you're saying that when you tap "iPAQ wireless" on the today screen, you do not see a bluetooth tab at all??
This has happened to me quite a bit. I've just gone to Start>Settings>Connections>Bluetooth to turn on and manage bluetooth without the iPAQ wireless manager. Glad to learn of this fix however, the wireless manager is much nicer and easier of an interface.
