With the recent launch of CardDAV, Google now offers similar access via IMAP, CalDAV, and CardDAV, making it possible to build a seamless sync experience using open protocols. Starting January 30, 2013, consumers won't be able to set up new devices using Google Sync, however, existing Google Sync connections will continue to function. Google Sync will continue to be fully supported for Google Apps for Business, Government and Education users who are unaffected by this announcement.
