I downloaded Lookout on my Droid primarily to protect my device against viruses. Now I find out it can also protect my car from thieves, if I happen to leave the phone in there!
This handy app helped Stalin Guzman of Paterson, N.J., foil the escape of a carjacker who unknowingly sped away with a tracking device left in the vehicle: Guzman's Android smart phone.
You'll get the full account in the video above, but the gist of it is that Guzman was held up at gunpoint right after he came out of his house to buy food for his family. He gave the armed robber his car keys and then rushed back inside to open up his Lookout app on his laptop. One of its features: phone tracking via Google Maps. He gave police the turn-by-turn movements of his assailant and in seven minutes, police had him in custody.
Guzman could have done other things as well: he could have activated an alarm on his phone (though the stealthy approach was probably the right one for this situation), wiped out all the data on the phone — and locked it remotely.
