Open Sourcing iPhone Apps ... WordPress is doing it!
Just thought I'd mention that WordPress has released the source code for their iPhone application. There is also some hoopla over a course that will be taught at Stanford on iPhone programming. Especially the latter makes it appear likely that the NDA will be lifted soon.
WordPress is also a big enough target for Apple to take down if they're really serious about it. So if nothing happens for a week or two, I think we'll see a lot of opening of iPhone source code.
