It does work, but over AT&T's network it will still be fairly slow, so especially in the first cycle where you are trying to call a bunch of recruits to see which ones are willing to be pulled down it will take you a long time to do it over an iPhone. Trust me, I have experience with it. With 4 open schollies and trying to make calls to about 50 players to see who was willing to be pulled down it took over an hour.
