Google no longer supports Exchange ActiveSync protocol to sync email, contacts and calendar stored on free Gmail / Google IDs with third party apps. If you have setup Google Sync via Exchange on your iPhone before Jan 30th of this year, you wouldn’t notice any problem, until you reset the device and try to setup your account using EAS again. Also, if you try to setup Google Sync on a brand new iOS device, you will be greeted with “Cannot get mail, the connection to the server failed” message.
