iOS GPS Location without carrier service neither wifi connection

Question

specifically this question is for iPhone only, basically the question is - does iOS location service still give the geo-location (lat, long) when the device has no carrier service neither wifi connection?

Answer 1

Yes it will give you the location using GPS and if the GPS signal is not there it still gives you the old cached location. So in any case it will give you the location.

Answer 2

So far as I know, the latest models (since 3? I think?) have an actual GPS so as long as you can "see" open sky it will be getting lat/long. Whether or not the related apps are able to function (whether it can load the maps, for instance) is another matter entirely.
