in giro ho trovato questo:
one of the problem that I get after migrating to Vista is getting Activesync to work using bluetooth. For some reason, Windows Mobile Device Center (WMDC) that's installed separately from Vista, doesn't allow bluetooth synchronisation to work especially if either your desktop or mobile device is running on widcomm bluetooth stack. Selecting 'Bluetooth' in the WMDC's connection setting doesn't work, at least for me. This is because while my mobile device detects my desktop via bluetooth, it cannot determine there's an activesync service (i.e. WMDC) running in the background in the desktop. In the good old days of Activesync, all I need to tell activesync to 'listen' to a bluetooth com port. There's no such ability in WMDC.

This registry hack, to be applied to your desktop pc/laptop, enables WMDC to bind to a bluetooth virtual com port (as you set this com port as the incoming port). Go to \HKLM\Software\Microsoft\Windows CE Services, modify the value name "SerialPort" from "Bluetooth or Infrared" to "COM4", where COM4 is the virtual com port associated to your bluetooth incoming com port. The number varies from desktop to desktop, so choose the right com port for your specific use
