If you’re using an iPhone (or other ‘net-dependent device) as your GPS, all your location/mapping/satellite info & pictures comes from the Internet; shut off the ‘net connection and all your iPhone can do is tell you latitude/longitude.

I remember using something called a “Map”.

I carry a real Garmin GPS when I travel. The GPS V and nuvi 500. Both have good base maps. My Droid has a good GPS and does cool stuff with Google maps, but I wouldn't rely upon it as my sole source of navigation.
