What is best 'stack' to connect to a "HTC TyTN 2" phone ?

Hi

What is the best BlueTooth stack (i.e. driver?) to connect a T60 Thinkpad with an HTC TyTN 2 mobile phone?

About the Thinkpad
Machine type-model: 2007-F4G
Mf part number: UT0F4UK
Serial Number: L3M4618
O/S: Windows XP Pro (SP2)

About the mobile phone:
O/S: Windows Mobile 6 Pro
Phone is also known as:

Kaiser: HTC P4550 / HTC TyTN II
/ Orange & HTC TyTN II / Vodafone VPA Compact V
/ Vodafone v1615 / SFR v1615 / Swisscom XPA v1615
/ T-Mobile MDA Vario III / AT&T Tilt
/ O2 Xda Stellar / EMobile Emonster S11HT

I have tried both the Microsoft software and also the Thinkpad (Broadcom?) version.

I can get the two devices to 'pair'. However I can not get them to run ActiveSynch - which I have tried initiating from the Phone
and it complains about COM ports. I got ActiveSynch to run ONCE but never again when run from the PC.

Any thoughts?

With thanks
