Specify iphone project

Hi, I've downloaded the free version of unity iPhone, with the promo, but I'm not sure if my project is now specified as iPhone/Android, since they've removed the separate program for iPhone. I've opened some iPhone example project, and an example of what I see then is that the resolution options are iPhone 4, iPhone 4S, iPad, etc., while in my project it's 3:2, 4:3, etc. How can I specify to unity that this is a mobile project, so that I can use things like touch, and use a 320/480 coordinate system for UI?

Thanks, Arne Gevaert Co-founder of Platypus Studio
