Tutorials/Help starting development (not publishing) for iOS?

Hi,

I'm interested in developing an iPhone game without necessarily publishing it. To be clear, I want to make a short demo or sketch of a game idea, so publishing it is completely out of the way.

I'm confused about what's needed though. The Unity tutorial on it begins to say I need some kind of developer account, but the developer account web page says I don't need one to develop, only to publish.

More importantly, I'm more interested in code. Can I use the basic input and multi-touch...
