title: iPhone SDK - wifi list
body: <p>this may be a newbie question...but I am in the world of MAC/iPhone development, I'm looking if there is anyway of retrieving a list of Wifi networks in the area.  For example, if the Wifi on the iPhone is on i want to get that list of Networks available.  I've searched through the Apple documentation but I can't seem to filter out what I need.</p>
  
  <p>Thanks.</p>
