Iphone Unity and Best book .

I'm new to unity , and was wondering if there is any difference from the normal computer unity and iphone unity ? Anything different with the scripts ?

And what is the best book so far , that will tell me how to learn unity javascript and other stuff ?

You're supposed to use separate pages for each question, but you should not make a new page. Your second question has been answered.
