I have an HTC HD2 mobile operating Windows Mobile 6.5.

 

I need to sync Google contacts from a collegues Gmail account without fully syncing all my contacts back up to his account.

 

My other colleagues' iPhones do this by adding accounts as sepparate address books, each fully separate and removable.  If I use ActiveSync it fully syncs the contacts up and down, me getting all of his and him getting all of mine.  If I add a Gmail email account through the HTC HD2's Mail application I don't get the option to sync contacts (the box is shaded out).  Please help.
