Looks like Apple has another lock screen bypass bug on its hands, one that affects the latest version of iOS: 6.1.3. It seems every time Apple tries to fix a lock screen bug, another manages to crawl out. This latest bug was discovered by “videosdebarraquito” on YouTube. As you can see, the bug was found on an iPhone 4, requires more than a few button presses to get it working. You’ll have to eject the SIM tray mid dial to access the device.
Like the previous bugs, it’ll only give you access to the Phone app and photos on the device and requires physical acess to the device.. A couple of folks have managed to recreate the bug on the iPhone 4, the iPhone 4S, and the iPhone 5. From the video, we see that the bug works through the pre-Siri Voice Dial system. iOS 6.1.3 was released to fix a series of lock screen bypass bugs but it seems Apple has yet to fix all the holes.
