When building a game for iPhone does it NEED to be built in only one scene or is it just a recommendation?
Also, if it is possible to create the game with multiple scenes is "Application.LoadLevel("Level Name");" an acceptable line of code to use?
No, it doesn't by any means have to be built in one scene. In fact, putting multiple assets worth of levels will likely slow down your load times making your user more likely to quit out == bad.
And yes, `Application.LoadLevel(""`) works fine. you can also pass an `int` as the argument.
