Services such as Find my iPhone are great as long as they work the way they're supposed to. Wayne Dobson, a 59 year old Las Vegas resident, has learned the hard way what happens when cell phone tracking programs malfunction. Owners of lost cell phones keep showing up at his door demanding their phones back. The only problem is, he doesn't have them. The problem seems to be isolated to Sprint cell phone users and due to a glitch that shows owners of lost devices that they are located near Dobson's home.
