    I have a Blackberry Playbook on my desk that I am trying to figure out how to crack. I also keep my Sharp EL-50 scientific calculator around. We had to buy that specific model because it didn’t have a persistent memory. We could turn it off and on in front of the invigilator and they would know there was nothing stored in it.
