I figured out the reason that you can take a picture of your iPhone screen WITH your iPhone. So when you're stranded on the side of the road, you can text a picture of your GPS location to people and they can save you.How cool is that?? Because I have the WORST sense of direction and when someone says "Are you east or west of 169?" I have NO idea what the answer is. A friend was driving by and picked me up on the side of the highway - it was my lucky day!
