I’m a big fan of Google Sync and have used it since its first release. If you haven’t heard of Google Sync, it’s a free service offered by Google that lets you synchronize your Google’s contacts and calendar event with your iPhone and iPad. The synchronization works seamlessly with iOS. Once you set it up, whenever you add a calendar event in your Google account, the event is automatically pushed to your iOS device and you can view in the Calendar app. Same for contacts. For any changes in Contacts (such as adding a new contact), Google Sync works in background and syncs your new contact to your Google account.
Now this free service gets even better with three new feature update, as Google announced in its blog.
