Features of the iPhone Maps App
Use Maps with Contacts.
Maps and contacts go together like peanut butter and jelly. For example, if you want to see a map of a contact’s street address, tap the little bookmarks icon to the right of the search field, tap the Contacts button at the bottom of the screen, and then tap the contact’s name.
Or type the first few letters of the contact’s name in the search field, and then tap the name in the list that automatically appears below the search field.
After you find a location by typing an address in Maps, you can add that location to one of your contacts. Or you can create a new contact with a location you’ve found. To do either, tap the location’s pushpin on the map, and then tap the little > in a blue circle to the right of the location’s name or description to display its Info screen.
Now tap the Add to Contacts button on the Info screen. You’ll probably have to scroll to the bottom of the Info screen to see this button.
