Search for Facebook on the iPhone App Store and you may or may not get the following graphic. It comes and goes. That screenshot below is the Facebook 3.0 interface. The app was submitted yesterday according to a Tweet by developer Joel Hewitt.
What its appearance on the mobile app store means is that Facebook 3.0 is coming to the iPhonesoonlike any minute now.
We've heard the app is coming, but it - for better or worse - won't include Push Notfications. Thanks Jason!
