I would highly recommend using Lookout on my Android phone. It is a great app. I recently had my work truck and trailer, full of tools and equipment, stolen. My phone was in the car dock when it was taken. I was able to use the Lookout App to locate the phone. In return I was able to locate my truck. I had my truck returned in less than 12 hours after it was taken. Unfortunately it was stripped of all valuable tools and the trailer was empty. But I have my truck. Thanks to the developers of Lookout!
