My sisters Blackberry was recently stolen, and the petty criminal used it to put a vulgar, retarded message up on her Facebook wall only a few hours later...
That means that the phone is still turned on, and sending out a signal, which means that the cell company knows where it is, which means they're just walking around with stolen property that's literally leaving a trail for the police to follow.
They obviously didn't steal it for the cash, because if they did it would be pawned off to some shmuck already, or at least turned off, so they're doing it for shits and giggles, which makes even less sense because there's no payoff at all... unless you count being beaten to within an inch of your life by a VERY angry woman and her friends a payoff...
Now, it IS only a phone, so it's not like the Fifth Infantry Division will be mobilized to find it, but seriously, are people (Petty criminals, more accurately) so BLOODY STUPID these days that they don't even know to either turn off, or get rid of, whatever it is they stole if it's TELLING PEOPLE WHERE THEY ARE??
