It is not inconceivable that someone is running something on their iPhone other than Apple's OS. Remember that there is a Linux distro for iPod. While I am not aware of any iPhone-suitable alternative OSes, it certainly can't be ruled out. It is certainly customary for a poll such as this to result in unforseen exceptions ("why didn't you list blah?"). If someone has indeed managed to mod their iPhone to this extent, then I'll ready my faux-surprise face. Indeed, I would be more surprised if there wasn't work being done by someone in this area.
