I jut did a backup (right-clicked my iPhone and selected backup). But how do I sync to iTunes so that everything in iTunes reflects what is in my iPhone? How do I make it so the iPhone Calendar and AddressBook overwrite the Macbook Calendar and AddressBook and not the other way around? And how do I know what's in the iTunes backup? i.e. what apps, addressbook contents, Calendar etc. We also have two iPhones in the house and somehow my apps are getting put onto my wife's iPhone.
