"Apple has released the latest update for iOS, version 6.1.3, which fixes a bug that allowed for bypassing of the phone's lockscreen security feature"
"The update fixes an exploit activated by making and then immediately canceling an emergency call on a passcode-locked device. A malicious user with access to the device could use the exploit, plug the device into a computer via USB, and potentially access the data stored on the handset. "
I think it's funny.
