Walking to work this morning (in the rain), my new iPhone asked if I wanted to join a network. When I looked, it offered me 4 pages of networks. Note that this was not in an apartment building -- I was under an overpass on E 61st Street, between 1st & 2nd Avenues. A new kind of urban density...

Page #1 Page #2 Page #3 Page #4

I then turned this feature off -- it's too distracting when walking around. Instead the iPhone uses my home network or Rockefeller's public network (iPhones cannot handle WPA Enterprise, so it cannot join the IT Staff WLAN).
