[.] A new way to sync Google Contacts
In addition to the previous methods to sync contacts with iOS devices, Google added a new protocol:
Starting today, we’re adding CardDAV – an open protocol for contacts – to that list. CardDAV enables 3rd party clients, like the iOS contacts app, to sync your Google contacts.
After testing it it, it seems this method is better than using Exchange. It is now possible to add relationships between contacts for use with Siri (“Call my wife”) which was not possible with contacts sync’ed with Exchange. Setup instructions are there.
