Just a quick question. Here and there in the forum, I saw random posts of people saying that you can always turn your ipod back to a normal state (i.e. not jailbreaked) by hard resetting it (pressing the home+off button for x seconds etc.). But I did not see anyone specifically saying that yes it does work and your ipod will be back to normal without absolutly no trace of a jailbreak attempt. Obviously, I'm asking this to know if we'll be screwed by a future Apple update. So can someone confirm?
