I don't know how many other people are fighting with this but I've finally found a solution. I'm typing this from memory but will update it later.

My setup:
MSI 1022 Laptop (XP Pro, SP2)
BlueSolei BT Stack (can't get the std .MSFT BT drivers to recognize my BT device)
2125 w/ WM5
ActiveSync (AS) 4.1

All of these directions are based on the premise that you have already successfully paired your phone to your PC and can successfully establish a DUN connection. For me this wasn't tough (refresh the services on the phone/PC and DUN is automatically added as a service on the PC) but post here if you are having problems with DUN & bluetooth.

1. Open AS and navigate to File->Connection Settings
2. Check the box next to 'Allow connections to one of the following'
3. Choose Com7 from the drop-down box. (This default COM could be different depending on your BT stack) and click OK.
4. Go to Start->Settings->Connections->Bluetooth on the 2125
5. Make sure bluetooth is set to 'Discoverable' You don't need to have OBEX auth. checked.
6. Choose Menu->Devices then menu->new and go through the discovery phase to find your PC. Here's where I got lost: When the services menu popped up it should say ActiveSync (make sure it's checked) but I had to 're-discover' my laptop a few times for this to say ActiveSync - before it would always say Com service or something like that. Hopefully you won't have this problem.

Here's where it gets weird:
4. Start a BT DUN connection to your phone on your PC. (you don't have to connect - just establish a communications link to the phone. But the cool thing is that you can be using DUN and AS at the same time)
5. On the phone choose start->Activesync then menu->Connect via Bluetooth

Sprinkle some fairy dust and it just may work.

My problem was always that I could pair my phone to my laptop and it would initially connect via Com7 but only when forcing a refresh of the bluetooth services of my PC on the 2125. I would see the phone successfully connect to the laptop and ActiveSync try to connect but the phone would drop the Com7 connection after a few seconds and AS would never be able to re-attach to the phone via Com7.

If I had to guess initializing a BT connection to the 2125 via DUN gets the phone 'talking' to the PC via BT. Manually choosing to sync using BT from the phone causes the phone to then 'see' the PC because of the pre-existing DUN connection and then successfully connect via Com7. All very scientific.

In my experience the connection allows you to browse the phone and do all the stuff you can do usually via a USB connection.

Anyway that's how I got it to work. I could very well be doing something wrong to make this so complicated, all I did was keep beating my head against this until it worked; and I still don't know why it worked.

Hope this helps someone out there. It's pretty cool to be completely wire-free now!
