I've bought a 3GS iPhone on PAYG from O2 to replace the unlocked 1G iPhone that I had. The iPhone has imported all my settings - everything is working, including email (which is a Google Apps domain email set-up specifically for download via IMAP) however my Calendars and Contacts do not work. They are blank. They are set-up to sync via Exchange ActiveSync and I have re-entered the password details, turned them off and on in the Settings, but still they do not download the data from Google. Any ideas how to get the new iPhone 3GS to sync with Google calendar and contacts?
