I have been playing with some crazy idea for a while. I know that exist a lot of anti-theft apps where you can send a message to your stolen and it performs a certain task like taking a picture or start an alarm or something like that.
So I have started to think about the possibility of a more radical idea like being able to send a sms to your stolen phone that would cause some kind of irreversible damage. Something that could fry your phone internal components like a killer overclocking.
I dunno, I just thought that it would be a cool sweet revenge.
