If you have an iPhone synced with Address Book.app, then you've been able to sync your contacts with Yahoo for a while now, but something that has been missing is Google sync. Sure, you can always use Spanning Sync, but we all want something free and built-into the OS. Well, those dreams are now true according to a new Google blog post and the introduction of Mac OS X 10.5.3.
On the Mac you normally sync your iPhone with, you will see a new option when you open the "General" tab in Address Book preferences. When you check "Synchronize with Google" you can enter your Google credentials and syncing will proceed. Apple and Google did leave some people out, however, as this new feature works only on Macs that have an iPhone synced with iTunes.
Thanks, Nathan and Ryan!
