Someone wanting to gain access to a locked iPhone can do so with a quick hack, as detailed by the video above.
You can see that a person can make an emergency call, and cancel it. From there, they can access different parts of the phone, such as voicemail. This is very similar to an old iOS 4.1 problem that allowed for bypassing of the lock screen through the emergency dialer.
It’s a quick process, but in involves some going back and forth into the emergency call screen. We’re sure Apple will patch this up. The good news is that I doubt the average chump that gets a hold of your iPhone will think to do this.
