Unity iPhone does give you the possibility to use unity to create an iphone game.

Without the license you can only develop for windows, osx and web

And yes, as with unity you need software to create your models, textures, sounds etc to use them in unity

Let’s say i want a person running can this be done in unity?

Ill be making some 2d games

the movement, collision and input control, yes.

But the graphics must be done in a graphics application.

Unity offers you the engine to develop the game but you must bring in the assets to create the visual and audio part

Optimally you would just download the free unity for desktop and learn it that way. This will give you a much more direct knowledge

2d is particularly tricky as Unity is a 3d engine. It is entirely possible, in fact, I’m only doing 2d games these days, but you will need some time to learn.

Also the small cash investment of SpriteManager2 saves you countless hours of work due to the present 2d animation system, sprite editor which even combines the distinct images for you etc
