I don't know about the iPhone specifically, but assuming it works as a standard wireless router,
there is no logical reason why it shouldn't work. Of course, computer technology often does not
work for no logical reason, but that is a different story.
The WNC2001 is booked into the network using a PC/browser once, then maintains these settings
until changed again. Basically, it is "permanent" until told otherwise.
