Over half the APIs introduced in both 3.2 and 4.0 were formerly private APIs. We've been having a lot of fun with them in jailbreak-land :)

This is a good demonstration of why the whole "private APIs" distinction is harmful. It allows Apple to continually be several steps ahead in application development, and it also makes the already capricious and arbitrary App Store approval process even worse.

I don't understand the problem here. This would only ever cause an issue if Apple were to take a formally public API and make it private.

oh the webs we weave, this is pretty hilarious
