Given all the developers I see bitching about this restriction (almost every iPhone one I know/know of, especially high profile ones..like apple design award winners (craig hockenberry of twitterrific fame)), I'd be surprised if everyone just forgot about that wee little detail. :)
I was flabbergasted to see the NDA restriction still applying after the final SDK was released (http://lists.apple.com/archives/cocoa-dev/2008/Jul/msg00855....) and since Apple is still pretty keen about the NDA, I have a feeling it's not that :)
