Some time ago, a friend told me his Nokia 5800 got stolen. He left it in his backpack and leave it on the floor for about 30 seconds. He was not far way, just a few meters. When he came back, his backpack was open and the phone away!

Well, after this, I was thinking what you can do against it. And I got an idea, which is a bit strange but funny and really cool, I think. Whether and how it works, depends on the hardware of the device. And of course: There is no 100% safe method. There's a trick against every trick


There has to be this thief detection application that you can start, when you have to leave your device alone for a while. You have to choose a short PIN and active the thief detection. After this, the app is checking the G-sensor. When it's got moved it makes a gentle piep tone. After this you have some seconds to enter your PIN. If you don't enter it, there should be a loud tone.


Ok guys. What do you think?

EDIT: Seems I choose the wrong forum. "Applications" would be better.
