A Canadian technical consultant by the name of Ade Barkah has uncovered a particularly weird bug in iOS 5 that lets anyone see a locked iPhone’s Camera Roll from the device’s lock screen. The only catch is that viewable photos must have a time stamp that’s newer than the iPhone’s internal clock.
If an iPhone’s clock were to ever roll back or get manually set to a time in the past, any photo taken after that date can be easily seen by means of the Camera app shortcut on the iOS lock screen.
