I've looked at the Wigle database about a month ago, and it seems
that while the database itself is a great source for geocoded SSIDs
(and more importantly, MAC addresses), the licensing is somewhat
restrictive.
With regards to the iPhone, another interesting question is whether
we can access the API that the field test app i using to show
currently visible cell towers with signal strength. This information
could then be used, similarly to Wi-Fi, to geolocate the handset.
Since the GSM network has better coverage than individual Wi-Fi
networks, this could be a more worthwhile technique.

There's news today that there might be something useful here for
building iphone wifi geolocation: http://code.google.com/p/iphone-
wireless/ it looks like it's possible to scan for an AP SSID:

ideally, if you have a db of locations of AP SSIDs then all you
have to do is scan and compare visible APs with known AP locations
to determine your location.
so the question remains, (aside from the skyhook/loki commercial
db) what is the best source of a db of geocoded wifi AP SSIDs?
Drew, Is wifimaps.com the best, current source? also, I'm
wondering if anyone has had any recent experience with the wigle db?

Do you or any of these others publish the associated datasets,
eg. under Creative Commons or other open license? Seems there's a
problem getting critical mass of data for such efforts...
We're releasing the wifimaps.com data under the GPL, as soon
as we can package it into a useful format!
The next question becomes -- what format do people want their
wifi locations in? WFS? KML? Something made-up? Again, I'm looking
for some kinda help on this project, as I'm in way over my head =_)
