It wont run iPhone OS as it is about as closed as they come and only carries support for the iPhone hardware, is a big no no no on that one, and Android is a flavour of linux, yes, and has already been seen in the wild dual booted on an N900, check out a google search and you will find. But as stated above, if some of the hardware is closed, and remains closed, you will never get full functionality out of any other OS as no drivers will be available.
