Can someone build an app that alerts me when ISS is in the sky above me based on my phones GPS location. Blackberry preferably.Mon May 17 23:05:10 via web

Just a great, great idea. I remember being in middle school and there was one summer when for 3 nights in a row, my friends and I would sit on the roof of someone’s house and watch the space shuttle travel across the sky. I haven’t done that since. Why? Mainly because I don’t know when to look up.
