If you happen to be using wpa_supplicant instead of NetworkManager or
Wicd, it's in /etc/wpa_supplicant/wpa_supplicant.conf. If you're using
Wicd or NetworkManager, I haven't a clue, and on my more cynical days,
I think maybe they ship the wifi records via dbus to some other app
that actually writes them.

By the way, between iwlist scanning wlan0 (or whatever),
wpa_supplicant, you can do a pretty good job of logging in if you're
not continuously walking from hotspot to hotspot to hotspot.
