It’s apparently 98% of the way finished. Here’s Hewitt’s own words:

Facebook for iPhone 3.0 is coming very soon. I can’t predict an exact date when I will submit to Apple, but I can say that I am about 98% done. So

what’s new in this update?

1. The “new” News Feed
2. Like
3. Events (including the ability to RSVP)
4. Notes
5. Pages
6. Create new photo albums
7. Upload photos to any album
8. Zoom into photos
9. Easier photo tagging
10. Profile Pictures albums
11. A new home screen for easy access to all your stuff, search, and notifications
12. Add your favorite profiles and pages to the home screen
13. Better Notifications (they link to the comments so you can reply)
14. Quickly call or text people right from the Friends page
15. Messages you are typing will be restored if you quit or are interrupted by a phone call

The one feature everyone is asking for, Push Notifications, is in development but it won’t make it into 3.0. You can expect it in a 3.1 update later this summer.
When I have submitted the app to Apple I will let you all know!

Sounds good, yes?
