HTC :: Need To Tether WM6.5 Wing To Blackberry 8320

I have a Blackberry 8320 that I must use for corporate email and I have to use the UMA feature to get phone calls while at home. I also have a T-Mo Wing with WM6.5 that I'd like to tether to the Blackberry to use for personal email, gmaps, etc. How can I tether the Wing to the Blackberry's data plan? I've tried pairing them with Bluetooth and I can see on the Wing the Dial Up Networking service from the Blackberry. I've tried creating a new connection, choosing the Bluetooth connection, but haven't been able to get it to work.
