If you are looking for fun with your friend's phone, here is an easy trick to read their SMS or to turn the phone off or to even play the music you like(Well it does many other things too). It works with Sony Ericsson, Samsung and Nokia.
Just download the bluetooth hack tool from: http://uploading.com/files/get/WEHH765S
(I have not yet tried the tool, as it was recommended by my friend yesterday, so have fun)
