Its my understanding that if your Gmail account had the EAS syncing enabled prior to their policy change, that it would still be available. This means that for those of you who had this working on your Lumia 920, or who have a Gmail business address, you should be able to just set the account up as you would say an exchange account.
It will fail to find your settings the first and second time you say next, but on the third you get a notice saying try again or 'advanced'. Pick advanced, make sure your username matches your mail address, and the use m.google.com as the server.
This this it should happily add the account and you'll still happily get all the EAS goodness you had before.
Google is no longer allowing users to enable EAS, but if you had it configured before or you have a paid account you can still use it.
Just means you have to do a tiny bit of configuration to get it added to your device, but even in this case its still a fairly easy and straight forwarded operation.
Personally when they announced the changes I jumped ship to Outlook.com and been loving it. But have tested now if adding Gmail accounts like an exchange account works. It does, so if your account was setup for EAS, then you can still enjoy it on your WP device!
