Right now, you have to pay big bucks for a turn-by-turn GPS third-party application (the Tom Tom app is a cool $100).

While the is quite good (as are other navigation apps in the App Store), it just doesn't make sense that Apple wouldn't develop its own Maps application.

Google Navigation is free and available to all Android phones, as is Ovi Maps for Nokia Symbian phones. And all Windows Phone 7 devices will come with Bing Maps.

Perhaps there's an iPhone Maps app coming down the pipeline later this year--or perhaps it is one of those 100 new features in iPhone OS 4 that Jobs didn't highlight--but as of right now, you'll have to rely on Google Maps or a third-party app.
