How do I sync my Google calendar with my iPhone? So I have set up my calendar on Google. I am trying to get it to sync those changes to my calendar application on my iPhone 4S. I currently have under "Settings > Mail, Contacts, Calendars" the following accounts: 


iCloud (Contacts, Calendars and 5 more..)
Exchange (Mail, Calendars, Reminders)
Gmail (Calendars, Notes)  


Fetch New Data is set to Push/Every 15 minutes. What am I not doing right? Thanks!
A quick search led me to this step-by-step guide to sync Google Calendar with iPhone.
