We announced that 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. You can read more about the Google Sync End of Life on the Google Blog. I've put together a list of common questions/concerns.
How should I replace Google Sync on my device?
Below are the recommended ways to make sure your Gmail messages, Google Calendar events, and Google contacts are always with you.
The Gmail iOS app is the recommended way to instantly receive your mail on your iPhone, iPad, or iPod touch. The app brings the best of Gmail with push notifications, multiple account support and search across your entire inbox. Download the app now or learn more about the Gmail iOS app.
To sync your Google contacts with your iPhone, iPad, or iPod touch, we recommend using CardDAV. You’ll be able to edit, add, and remove contacts from your device and keep them in sync everywhere you use them. Get started.
We recommend syncing your Google Calendar using CalDAV. You'll be able to view and edit your Google Calendar using your iPhone, iPad, iPod Touch, or iCal on a Mac computer. Get started.
My Google Apps account is no longer working with Google Sync.
Google Apps for Business, Education, and Government customers can continue to set up new devices with Google Sync after January 30th. If you are having trouble accessing Gmail via Google Sync on your Apps account, please contact your Apps administrator so they can contact your dedicated support channels.
I recently restored my device or upgraded to a new device and Google sync is not working.
If you have recently deleted and then restored your device, this will count as a new connection and you will no longer be able to access Google Sync. If you have purchased a new device and tried to re-add Google Sync, this also counts as a new connection. Connections are based on devices and not accounts. If you have an iPad with an existing Google Sync connection and a new iPhone, the iPad will continue to work with Google Sync, but the iPhone will not be able to add the new account. Below you will find how to replace Google Sync on your device.
