Address Books
The Address Book is where you can store contact details in personal address books. By default the Contacts and the Emailed Contacts address books are created for you but, you are able to create additional address books.
Only a name is required to create a contact in your address book, but you can create detailed contact cards that include full name, multiple email addresses, work, home, and other addresses, phone numbers, and notes about that contact.
The Emailed Contacts address book can be automatically populated when you send an email to a new address that is not in one of your other address books.
