If two iPhones (or whatever other kinds of device you might care to talk 
about) are connected to a single wifi point, regardless of whether or 
not they can see the internet, then so far as talking to each other is 
concerned, they're on the internet. Obviously, trying to connect to 
anything that isn't also connected to the hotspot will fail with the 
usual "So sorry, can't figure out a way to get there" result. If they 
connect to two different hotspots (assuming there's no connection 
between the two hotspots) then they're both going to be "blind" to each 
other's existence.
