To take advantage of the flaw, hold down the power button on the locked device until the power off slider appears, then whip the Smart Cover on, open and tap cancel. Fortunately for iPad owners, the rest of the tablet remains locked-down, but the main problem here is any sensitive information left on-screen.
If you unlock the tablet to the main screen, you won't be able to open new apps, although anyone feeling particularly nefarious can apparently delete apps from that meticulously arranged home screen.
