From Mobile Breeze:
FREE FOR A LIMITED TIME GET IT BEFORE APP IS BANNED
Freak out your friends with this prank app that makes them think you can pinpoint their location on a map just by using their cell phone number!
Prepare to be the center of attention at any party with this prank; expect the following reactions from your friends: "OMG...get out!" "That's creepy!" "Looks like something from the CIA!"
IMPORTANT: Internet connection required for ipod. THE TRICK ONLY WORKS WHEN THE PERSON YOU ARE PRETENDING TO TRACK IS NEARBY. The application basically shows your location on the map, but since they are near you, they think the application was able to track them. video: http://www.youtube.com/watch?v=k2Uk7sKbLn4
The Free version is identical to CellSpy except after the 3rd use you to wait 3-20 seconds for satellite connection
