How to sync google holiday calendar to your iphone 4

First of all, I am assuming that you are already syncing your google calendars to your iphone. If not, follow these steps at http://weewahlam.blogspot.com/2010/10/syncing-multiple-google-calendars-to.html

When syncing, you would probably be unable to sync google singapore holidays calendar as it appears to be a type of calendar which was not allowed to sync. Beats me.... I wonder too why they disallow it for syncing.

Anyway, I have found a way to work around it by using 2 things. First, use ical and secondly, use import calendar feature on your google calendar.

1. Go to the google Singapore Holidays calendar and copy its ical link.
2. The create a new empty calendar and name it something. I call it my_imported calendar.
3. Then click import calendar, cut and paste the ical link and import into my_imported calendar.
4. Then sync as usual and it works!
