So I do consider myself above average smart with technology so this has really stumped me. To my knowledge there is no way you could recover history off of a device after it has been cleared, because there is nothing storing it. Alright well here is the back story. I go to a school where we use iPads in the curriculum. About a couple months ago the school instituted these random iPad checks where they would take students iPads for a couple hours check them and then give them back. Yesterday this happened to a friend of mine, that night he received an email home with different websites that he had been to that are inappropriate to say the least. The thing is that when they put the iPad checks in place he factory reset his iPad not to mention clearing the cookies cache and history before. The only thing I can think of is that they pre-installed some hardware before that kept a list of history. How is this possible?
