Without being to obvious at some of the other places that I spend my time, I came across this article from someone who is know to...speak from both sides of his mouth so to speak.
I find it hard to believe that there is much validity to his article, and if it were me, would be rather pissed if someone was falsehoods regarding my work.
From what I know, this is the foremost place to get information regarding the iPhone. I don't know who is on the Dev Team specifically, but I do know that a lot of hard, and at many time under appreciated work goes into them being able to pull of the magic that they pull off.
Never the less, here is the article, and in case anyone finds any relevance or truth to it, then of course please post to enlighten me and others.
