Some-One

I don't know if you are still trying to find a free PIM but I know a very good one. It is PIM Xtreme and you can find it at http://forums.xisto.com/no_longer_exists/ It is Open Source licensed under GNU GPL, and that means it is free. You can handle contacts, calendar, events, to-do lists, and even financial stuff. I'm not sure about sync but you can export to iCalendar format, which it's supported by Google Calendar. Hope it helps!
