Was in the mountains today, far, far outside of cell range. I popped open Maps, and had it locate me. Found me in a few seconds, got the blue dot. But, my map was just a grid, of course, since it uses google maps. I put a pin down anyways, to see what it did. got back to town, and the pin I had placed was exactly where I thought it would be, up in the mountains. Obviously, the GPS chip can give the iphone coordinates even without cell service or internet. Why can't we have locally saved maps then and use them when we are out of range? Makes no GD sense.
