In 3.0 they have Auto-Fill for Safari. You go into the settings app to turn it on, and it needs to tie into an entry in the Address Book.
I went into the Settings app to set up mine, and I noticed that it already had guessed who I was. Was it doing this using something in the API? If so, how do I access this function?
My iPhone syncs up to Address Book on my Mac, and the desktop app knows who I am. Does the iPhone now look at this same property?
