The iPad 2 Smart Cover accessory can be used to gain access to a locked iPad, 9to5 Mac reported on Friday. Here’s how it works: take a locked iPad 2 and hold the power button until the “Slide to Power Off” message appears, and then close the Smart Cover. When you lift the Smart Cover again and tap “Cancel,” the iPad 2 will allow you to access the last application that was open. This could be a big threat for anyone who was accessing contacts, viewing a website or checking email before he or she locked the iPad. The good news is any would-be thief does not have full access to the tablet, only the last application used. The bug has been spotted in iOS 5, although 9to5 Mac said it has also received reports from users noticing the flaw in IOS 4.3. Currently, the best fix for concerned users is to turn off Smart Cover unlocking entirely. A video of a Smart Cover unlocking an iPad 2 follows after the break.
