This SDK announcement really inspired me today... the iPhone is unbelievable for this stuff, and I don't want to sit back and watch it fly, I want to write apps. Unfortunately, I don't have the faintest idea how. How do people get started writing apps? My ultimate goal will be to create apps in Xcode, so my question is where do I start if I don't know anything. Thanks, hopefully some seasoned developers can help me get started!
