Vista bluetooh sync with windows mobile device center and ..

Unable to connect my dell Axim X30 with windows mobile device center using
Bluetooth. I can sync perfectly with USB but not BT. My computer sees the PDA
an so does the PDA.I have sent files using BT between the computer and the
PDA. I have tried editing the registry like red on other threads but still
the WMDC doesn’t recognize my PDA. When I go to Bluetooth devices and check
the services my PDA offers it only shows serial port, not active Sync like it
is supposed to do according to other threads.

HELP Please
