Over the weekend I added the missing parts to make calendar synchronisation over ActiveSync working mostly. So far it works for single events only, participants are not yet handled and some fields are missing too, but for single events it works perfectly. Over the next week we will fix the missing parts and the we will finally be able to have all calendar data on our mobile phones.
For me this is a major step forward, as I now can schedule all my meetings from my mobile phone and get an immediate update about new meetings when I'm not in the office.
Really nice if you ask me!
If you like to live dangerous, feel free to update from svn and help us testing. If you are scarred about your calendar data, better way until the next beta release.
