If you have the tablet tehthered to the phone, you can use the email program to sync with your email. (if your email supports POP or IMAP, which it should if your phone is synced with it). You can download GPE Calendar and Erminig, or MCalendar, to sync with Google Calendar. Not sure if this is what you want or what your phone uses for its calendar. Basically the files would be shared over an internet connection, not a straight connection between phone and tablet.
