In the latest issue of "The Economist" today, I read about this website called "Brooklyn Space Program" where these people in New York put an Iphone in a box, and then in a balloon, and sent it up into space. It's a great video. To watch it go to http://www.brooklynspaceprogram.org. The balloon went up 19 miles before bursting. The phone had a parachute attached to it for if and when the balloon burst. The phone had a GPS added to it so that it could be found after landing back on earth. It landed only 30 miles from where it went up. The GPS on the Iphone is something that will appear on Iphones in the future.
