While not the most glamorous of mobile phone features, the iPhone’s address book in none the less useful. Synchronising with either your Mac or PC, your iPhone contacts book allows you to carry your whole address book around with you for easy retrieval.

Using the iPhone’s intuitive touch screen, users can easily flick through contacts quickly and easily, add or remove individual details and even dial, email or send an SMS to a contact directly from the address book.

In addition to that, the iPhone 2.0 software brought with it the ability to search for a contact by typing in the person’s name rather than scrolling through the entire address book to find a single contact. Users can also make certain contacts “favourites” to keep their listings at the very top of the list for easy access.

Updating a contact on the iPhone will also automatically update that contact’s information the next time it is synced with the user’s computer to keep both address books completely up to date.
