- Click "learn more" next to "download your information"
- Some dialog boxes make you click ok
- FB says it needs some time to collect your information, and will send an email when it's ready
- You get an email with a link to the zip file.
One thing I'm curious is how much history is retained. I've been on facebook since at least 11/2005  and over that time they've gone from about 5 million users to 500 million. I'm sure they've changed a lot of systems since then, and it wouldn't be surprising if they couldn't pull my oldest data. So:
- Events: my oldest listed event is from 4/2006. I think I attended events before then, but I don't remember.
- Wall: for some reason my wall only goes back to 6/2008. With the normal web interface, after a lot of "show more posts" clicking, I determined that my wall goes back before then to at least 4/2008. I could keep clicking and find out how long ago it goes, but it's not much fun.
- Messages: my first message is from 11/2005. That's probably the first message I got.
- Notes: these go back to 2004, when I was definitely not on facebook, probably because facebook trusted the dates on the posts imported from my rss feed
- Photos: these are only albums I put up, and go back to 2006. Whatever profile picture I had before the one I put up in 12/2006 is apparently gone.
 Dating things like this is hard. I have a blog post from 11/2005 that mentions being on facebook. I think I remember being on facebook when it was opened to high schoolers (and all the complaining about how younger people would ruin it), which facebook says happened in 9/2005. Apparently facebook won't tell you your join date.
