Prey: track your stolen laptop or Android phone
Just found this new software that seems to be pretty cool.
Prey- An awesome application to track your stolen Laptop and android phone | Linux | Unixmen
Prey is a lightweight application that will help you track and find your laptop and android phone if it ever gets stolen. It works in all operating systems and not only is it Open Source but also completely free. so basically you install a tiny agent in your PC or phone, which silently waits for a remote signal to wake up and work its magic.
I might have to give this a try.
