Interesting. Turned on my SE3 in airplane mode, location services on and walked outside to use the Maps app that came with the iPhone. The location came in showing lat-long, but no map. it doesn't need much, the base map with no additional detail would be good, but a bare page with nothing but the lat-long coordintes showing is a bit too bare bones to be useful.

My Garmin Geko has more usefulness because I can add waypoints as reference points.

Any better apps out there that show map features when in airplane mode?
