Pragmatic Programmers pull iPhone book due to Apple NDA
If you fancy having a go at writing apps for the Apple iPhone and want to learn how, then you will be required to agree to Apple’s non-disclosure agreement while installing the iPhone developer tools.
The bad news is publishing company Pragmatic Programmers is cancelling their iPhone book because of the Apple NDA.
Normally once an item is release the company NDA is lifted, but not in the case of the Apple iPhone 3G. Apple has no intention of dropping the iPhone NDA anytime soon.
This is why Pragmatic Programmers have pulled their iPhone book, but they are still looking for ways to get the content out there; unfortunately this won’t happen in the short term.
