Users who have a passcode on their iPad 2 running iOS 5 should be aware that in one particular circumstance, the passcode can be bypassed and allow limited access to the iPad 2 simply by using a smart cover (or any similar cover that uses Apple's magnet-based system for waking the iPad 2 from sleep), a German Mac website reports. The passcode barrier works as expected if the iPad is simply put to sleep, but an incomplete powering-off sequence leaves the device vulnerable.
