If your existing Bluetooth device / stack does not work with blackberry here is a way out.

Buy a simple Bluetooth dongle, restart couple of times, load Microsoft Generic Driver and find it detected by your Blackberry Device Manager. Rest of the approach to use this additional device is same as else where in the forum.

Indian Users: For configuring your Airtel/ Vodafone on your BB and Laptop, please read the following:

First the problem:
Blackberry may not work with all of the bluetooth adapters new laptops have. The reason for this is as simple as: Blackberry Device Manager can only recognize Microsoft Bluetooth Enumerator or as Generic Bluetooth Radio and NOT any other Toshiba, Dell or any other Bluetooth stack on your laptop.

How to know what you have? Check under "Manage" of My Computer and check out under bluetooth.

You can find many of such description on Blackberry sites w.r.t your device and configurations.

Alternative?
Cheapest and fastest is to buy a Rs. 200/- worth generic USB Bluetooth dongle. Put it in your PC and restart your laptop couple of times. You should see it detect this device under the above category.

Else, you could install a driver (with the CD it came with) and uninstall its drivers and restart machine couple of time.

Once done, you should pair it with your blackberry. Make sure you add the blackberry device from your laptop instead of the other way.

Your Blackberry Device manager would pick this up and show in your "Connections". If not, re-install Device Manager and see it come up.

Once up, you can use it for Synchronization between both devices.

Adding the bluetooth modem is similar to mentioned here except that you need to pick up 'Standard Modem' on Bluetooth. However, the remaining settings continue to be the same.

Ensure under the "Phone and Modem options" under Advanced Tab you have this entry +CGDCONT=1,"IP","airtelgprs.com" and the number to dial is *99#
