Some of us last year tracked our iPhone 4's last year on a site called Flight Aware it's a popular website for people who fly or someone who wants to track their family member or item in flight. Also LiveATC is a national Live feed for people to listen to their local Air Traffic Controler/Pilots at the local airport. I use both either when I am flying to different areas or just tracking packages to me.
