I own Unity Pro and Unity iPhone Pro and have been using them on my Mac.
I would like to download the PC version and use it too, is that allowed with the current license? I know I cannot develop iPhone projects on the PC, is that correct? In any case, I want to use Unity Pro on the PC, can I do so?
yes you do need the mac to compile for iphone. Though you can use the unity remote for testing in pc if i remember right, but the last time i tested that there are some things about it that are misleading. i believe when you using the unity remote in windows it still uses mouse for input or at least things like monobehaviour OnMousePress work, where they wont work on the actual device.
