Today, Google announced that they are adding Gmail support to Google Sync. This will allow users to get push notification for their Gmail emails on both the iPhone and iPod touch.
Using Google Sync, you can now get your Gmail messages pushed directly to your phone. Having an over-the-air, always-on connection means that your inbox is up to date, no matter where you are or what you’re doing. Sync works with your phone’s native email application so there’s no additional software needed. Only interested in syncing your Gmail, but not your Calendar? Google Sync allows you to sync just your Contacts, Calendar, or Gmail, or any combination of the three.
If you already have Google Sync set-up on your iPhone for syncing Contacts and/or Calendar… you should be able to just toggle the Mail option On and the push notification will be automatically enabled. If you do not have Google Sync set-up yet, check out Google’s guide HERE.
Google Sync does use an Exchange account so, if you already have one Exchange account set-up on your device… you are out on Google Sync.
