I was wondering if two-way synch between Erminig and Google Calendar would be reliable enough for me. It looks like perhaps not - possibly Google's slightly changed the way they process data and broken the interface gData uses?

I've started looking at the Google Tasks API that's available, but I'm hardly much of a programmer so it's unlikely anything will come of it. I would really love a reliable app that could synch both Tasks and Calendar between N900 and Google, and I think a lot of the logic from Erminig would be transferrable.
