xda orbit

Hi Guys. Got a little problem here: just got a xda orbit phone (O2 ,windows/ yes, I know , but its cool) and it doesnt seem to be communiocating with my powerbook (contacts, calendar, file transfers, nothing works). Would be oblidged if anybody had any suggestions apart from the obvious, to send the phone back. Thought of getting virtual pc, but dont know if it's gonna work and can be expensive!
Any help very welcome, thanks
