WM5 Wireless Modem for WM6?

[altalk]

Saw some earlier posts on this but haven't seen where anyone has figured out how to get the old WM5 wireless modem on WM6. Has that been done? For my applicaiton the new internet sharing simply won't work - or I haven't figured out how to get it to work anyway. I can connect to internet sharing just fine. I can get on the web and all works. However I have a tunnel application for my job that I need to use through the cell phone connection. When I start this applicaiton, the PC gives me the blue screen of death. It is repeatable. Doesn't happen with the WM5 wireless modem connection or any other connection to the internet I have ever tried - just this new internet sharing thing on WM6. I actually use the USB link so it isn't a bluetooth issue. Just something in the internet sharing that blows my PC up. Any thoughts would be appreciated - or a method to install the wirless modem on WM6. I'm using the standard ATT upgrade ROM - stock model.

Thanks.
