Hi, Mikel and Lumsdoni
I think that we have other similar problem: with the ROM A12, or A04 in other languages, when deactivating the "UPS to PC" option (in control panel, third tab) I got an error "Error deactivating RNDIS" only if Widcomm stack is installed.
Is not a great problem because there is no reason to do that, because RNDIS active sync connection system is better that the old WM2003 PPP serial system.

I think the issue is that PPP tries to use COM8 because it think must be free because Microsoft stack uses COM6 and COM7 but we are using COM7 and COM8.

If anybody has this problem (Lumsdoni for example) the solution could be (not tested)
1. Close BT Manager and turn BT off.
2. Open registry with Resco Registry Editor or your favorite tool and make the following changes (no need of soft reset after them):

[HKLM\Software\Widcomm\BTConfig\Applications\0001]
Change ComPortNumber from 8 to 7

[HKLM\Software\Widcomm\BTConfig\Services\0001]
Change ComPortNumber from 7 to 6

[HKLM\Drivers\BuiltIn\Serial8]
rename to [HKLM\Drivers\BuiltIn\Serial6] and change these subkeys acordingly
"FriendlyName"="Bluetooth Serial Port COM6:"
"Dll"="btcedrivers.dll"
"DeviceArrayIndex"=dword:00000006

This will also solve the problem with the GPS Mikelspikel have just commented.
