I think that means unreleased Apple software... like Firmware 2.2.

Nope, that's not what it means. Nowhere does it say it's restricted to only Apple-written unreleased software. It covers ALL unreleased iPhone apps, including apps that are unreleased because Apple refused to approve them.
This revision addresses a common complaint many developers have had; the NDA was so broad it prevented them from talking and sharing ideas and methods to write better software. So this change is a good thing. But this change does not help those developers who write code that Apple decides is too competitive to its own software and does not approve. They're still prevented from talking about why their software wasn't approved. And that's bad.
