Iphone developer program: does it require a business license

Paying the $99 does not give you any additional content or lessons. You already have access to the Apple-supplied sample code. The SDK only provides the ability to test your application on actual hardware, and it allows you to submit applications to the App Store.

The best place to go for beginning tutorials is the Stanford CS193P course which is available online through iTunesU. I would download all this content soon, as it is not guaranteed to be available when the next term starts.

Other than that, I would Google the exact terms that you had in your question: "Open GL ES" "iPhone" "cocoa touch tutorial" There's a ton of content available.

revised response: This info is readily available on the iphone developer application page. Both accounts allow ad-hoc distribution. The enterprise program allows in-house distribution or proprietary apps for companies with 500 or more employees.

original response: You have to go for the corporate program. It's the only one that allows you to distribute apps within an organization as far as I know. The individual account is only for apps that you intend to sell in the app store.
