Using multiple Google calendars on iPad/iPhone
Unfortunately, the iPad is not able to handle more than one Google calendar from one single account. It automatically picks the first created calendar and ignores the rest.
Here’s an easy solution to get it working.
HOW TO FIX:
1. Browse to http://www.google.com/calendar/iphoneselect
2. Select the calendars you want to use on your iPad/iPhone
3. On your iPhone/iPad go to “settings” > “Mail, Contacts, Calendars” > “Add Account”

4. Now choose for “Other”.

5. Choose “Add CalDAV Account” and use the following settings:
- Server: www.google.com
- User name: [YourAccountName]@gmail.com
- Password:[YourPassword]
- Description: [displayname you want to use for this account]
