Sync Google Calendar (in a good way) with iPhone (iCal and Outlook)

I have had quite some trouble getting my calendar in sync on all my devices. I want to use Google Calendar in Apple iCal (my home/work computer), Microsoft Outlook (work computer), iPhone (in my pocket) and through web based Google Calendar.

Outlook sync is solved with Google Calendar Sync for Outlook.

My headache were then Apple iCal and the iPhone. I know one commercial solution but I don´t think I should have to pay for this.

So I started to test Google’s guide with CalDAV. This got iCal in sync with Google, but my iPhone could not add new events in this calendar (oddly enough). It created a new calendar on the fly. Not a good solution for the iPhone.

Today, I found NuevaSync! Their service exposes Google Calendar as a Exchange ActiveSync service. It’s still in beta but seems to work quite nice.
Google now supports ActiveSync!
