iPhone Passcode bypass bug discovered for iOS 6.1.3

Apple recently released iOS 6.1.3 which included a fix for the passcode bypass bug that would allow an unauthorized person to access the Phone app on a locked iPhone. One day after the update, however, Matthew Panzarino of The Next Web is reporting that a new bypass bug has been discovered, this time by videosdebarraquito.

The passcode bypass in the previous versions of iOS 6 required a series of well-timed taps and button presses. The result was full access to the Phone app on a locked device without entering the passcode. This new bug (not quite new, it seems to have existed prior to iOS 6.1.3) requires a sequence that’s a little easier to execute as can be seen in this video. For some reason, this bypass seems to to be more difficult to accomplish on newer, Siri-capable devices.

A new lockscreen bypass has been discovered in iOS 6.1.3, notes iPhone in Canada. Unlike the tricks discovered in iOS 6.1, the new one appears to affect only the iPhone 4. It also, unusually, involves popping out an iPhone's SIM card while using Voice Control to dial an emergency number.
