Does anyone else see the irony in the news that Apple has finally added copy/paste functionality to the iPhone? This is the fundamental building block of all productivity in the Apple-style GUI. And they're finally getting around to it in version 3.0.
Anyway, if you're into the iPhone and the whole Objective-C thing, it's time to play with the iPhone SDK 3.0 beta. It's available here, and it includes support for all those new features. A fresh roll of dimes to the first person who integrates turn-by-turn directions into their application!
