See my instructions in my thread here:

http://www.utstar.com/pcd/downloads/...yncMode.sa.CAB which will allow you to switch from RNDIS to Serial, thus enabling you to sync with WMDC.
Otherwise, without running the patch and switching to Serial, the Axim will connect to the PC, but it won't set up a partnership nor sync any data, despite the dummy "Synchronized" status or "Connected" status, which are, in this respect, meaningless.
