The latest version of Mac OS X, version 10.5.3, adds the ability for iPhone users to sync their Address Book with Google Contacts.
According to the Official Google Mac Blog, a new Address Book preference option appears after the installation of 10.5.3, allowing a user to enter his or her Google account name and password, after which the contacts will automatically update every time the iPhone is synchronized.
It is presently unclear why the feature has been added, however, Apple included Yahoo! Address Book compatibility when it opted to include Yahoo!‘s mail service with the iPhone last year.
