I have tried this before but didn't get anywhere.
I have a Google Apps account of my own domain that I use for email, calendar and contacts. I sync all of these with my iPhone.
I would like to sync Facebook Events I am attending/maybe attending only to another calendar (separate colour) within my Google Apps account calendar. I dont want to have to export to ICS etc. everytime a new event comes up.
I have also tried using http://www.fbcal.com/ but this wouldn't show events with Google Apps.
[Follow Up Edit] Now that the event issue has been sorted out, thanks to eventbusyfix the Facebook Events are working in "other calendars" within my Google Apps calendar. How can you sync this over the air to an iPhone? I only ever see the options to sync your main calendars.
Oh, while I'm at it what about syncing Facebook birthdays as well (not export)?
