I remember Nikolaus mentioning some work on CoreLocation in MySTEP:
http://www.quantum-step.com/download/sources/mystep/corelocation/
From what I can tell, it's using GPS, and is implemented as client code in the
framework, and the code actually talking to GTA04's hardware inside a daemon.
Regarding WiFi -- yes, at least iOS and OS X use wifi to do geolocation.
There's several commercial outfits that provide this service to third parties;
to my knowledge, Apple used to use SkyLink Wireless in iPhone 2G era while
rolling out their own service.
Google has their own service they use in at least Android, and I suspect also
in Chrome; collecting data for it during capturing StreetView images got them
in trouble in at least Germany.
Google's API is called Google Maps Geolocation API, and it's a commercial
offering.
https://developers.google.com/maps/documentation/business/geolocation/
"If you do not have a Maps API for Business agreement covering the Geolocation
API, you may use a free quota of 100 requests per day for testing and
development only."
I don't think that's usable in our case, especially since every application
should include a distinct API key.
Unless there are free wifi hotspot databases out there, I don't think this can
be done any other way except how Nikolaus did it: by reading information from
an external GPS device.
