Just start building something. Start small and add to it as you learn. That's what I did about a year ago but I had previous programming experience. A year ago I had never owned an apple product and had never seen objective-c, now I have 5 apps in the app store, one of them in the top 50 for travel. It's been a lot of work but the first step is to start. Get a macbook and an ipod if you don't already have one, some books if that's how you like to learn (doesn't really matter which specific ones) and create something. Start building something that you would use or something that already exists. That way you are more focused on learning how to make it work rather than figuring out the specifics of what it is you are trying to build.
