There are no SDK snippets or API details posted. The only references to code are from the Java API and a general snippet of C code that the iPhone happens to support but are simply the BSD socket methods.
so, how was this legit with the iPhone NDA?
The article or the dev camp? My (non-legal) opinion is that the article gets into NDA-land when they talk about available connection API's and the return values of the accelerometer. It is also my opinion that the dev camp probably had more significant breaches, but if you don't hear developers talking at dev camp, did they really talk? Finally, it's also my opinion that it is silly that we even have to question whether someone breached the SDK NDA. Come on Apple lawyers. Fix this already.
