Finally Apple has approved the 3.0 version of the Facebook app for iPhone! I had to delete the 2.5 version from my iPhone and reinstall it from the App Store to get the new version, probably some kind of caching problem at the Apple servers. (It still showed the old version in the App Store but I got the 3.0 version when I installed it).
Now I will test some of the new features before I go to bed!
