If you’ve recently set-up Google Mobile Sync to synchronise your Calendar and Contacts with your iPhone over-the-air, you may have noticed that only one Google Calendar is being synced. It is possible to set-up Google Mobile Sync to sync up to five calendars, though (the maximum the iPhone supports) – you just need to make a configuration change.
Google Mobile Sync can synchronise both personal and public/shared calendars – here’s how to do it.
On your iPhone, open Safari and browse to m.google.com, then tap the Sync icon.
Tap “Sign in with your Google Account” and enter your Gmail/Googlemail login details. Tape Done to continue.
A list of devices set up to sync will appear (you can configure more than one – iPhones, Windows Mobile smartphones, and so on), so tap the one your want to edit.
You’ll see a list of Calendars under My Calendars and Shared Calendars. Tap to enable the calendars you want to sync and tap Save at the bottom of the web page.
If you use Push, the changes will take place automatically, or when you next open the Calendar app otherwise.
