@rudeboy is correct, it is possible but you are most likely going to run into alot of situations kindly referred to as unresolved issues during the syncs when you have to manually tell it which information to accept and so on and so forth.
Microsoft discourages this unless you are running Mobile Device Center on Vista which tends to play nicer with multiple devices. If you search the Windows Mobile pages on Microsoft, they have decent instructions which come with the usual disclaimers and stuff. Good luck.
