Apple has finally dropped the long withstanding Non Disclosure Agreement (NDA) that had been set in place for iPhone developers.

Up until now developers haven’t been able to openly discuss or write books/blog posts on the iPhone SDK and development practices. Because Apple had kept this NDA in place, they were pretty much sewing developer’s lips shut, and telling them they can’t talk about anything. Some sly developers were paying each other small amounts of money so they could call each other sub-contractors, and discuss development.
A new version of the NDA should be released next week, which will still be in place for unreleased third-party software and features.
