Back in February Google announced support for ActiveSync. Basically if you want to have Calendar and Contact pushed to the iPhone (or any device that supports ActiveSync) when you make a change online or if you are on your iPhone and make a change, this is done by ActiveSync. Now that ActiveSync is working how do you set up your iPhone to take advantage of this? This is for iPhone 3.0 and up.
1. Make sure your device has version 3.0 firmware or above. You can check your current version by going to Settings > General > About > Version. To upgrade, follow the instructions at http://www.apple.com/iphone/softwareupdate/.
2. Perform a sync with iTunes to ensure that Contacts and Calendars from your iPhone are backed up to your computer.
Note: Mail sync is not yet supported. You may receive error messages if you attempt to turn on Sync for Mail.
Getting Started
1. Open the Settings application on your device’s home screen.
2. Open Mail, Contacts, Calendars.
3. Tap Add Account….
4. Select Microsoft Exchange.
