It's in vcard format.
In order to get around this and overcomplicate things, I had to get my N900 out and pair it w/N9 then sync calendars through bluetooth. But there is bug with this method, all events show up in N9 a day later!? Someone please file a bug for this as I do not know how. Other users on nokia discussion reported the same result when syncing calendars from another device to N9 using bluetooth.

With contacts things went smoothly by syncing w/N900.

Why can't it just be able to import ics and vcard files like my n900?! It bothers me that I need another device to set up my phone.
