[Geowanking] iPhone Geolocating technology?

The iPhone is using Cingular's network, which is a U-TDOA location-enabled
network that might be used to locate the iPhone. But is there a build-in
location app on the iPhone already?
It also has the embedded Wi-Fi. Wi-Fi can also be used for geo-location:
I don't think Skyhook (Jed, correct me if I'm wrong) is for mobile devices
like cell phones (at least not yet.)
Navizon is however. It has an API for mobiles like cell phones and
PocketPCs. See the Navizon Developer section:
PlaceLab, the open source project, also has an API that is for mobiles
Ekahau is really for micro/pico-level Wi-Fi positioning that requires RF
fingerprinting and site surveying. Navizon, Skyhook, PlaceLab are based on
triangulation (or proximity).
Plazes is Wi-Fi location enabled? I know it uses cell towers.

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...
