Wow, HolgerN, thanks for picking up on the development!

A while ago, I tried running Erminig 3.0 (from the repos, check garage) on the N900 (Maemo5), but I was not able to get it together. I believe it was something with the built-in calendar in Maemo4. However, I remember some fixes for the Google Accounts handling was included in the 3.0 version. The source/data can be found here: https://garage.maemo.org/frs/?group_id=702. Hope to be of help!
