A Brazilian iPhone customer demonstrates the quick method to circumvent an iPhone’s passcode-protected lock screen: tap the “Emergency call” button, then enter three pound signs, hit the green call button and immediately press the lock button. That simple procedure gives a snoop full access to the Phone app on the iPhone, which contains the address book, voicemail and call history.
Impress your friends with this hack while it last. Apple will push out software to remove this backdoor, and possibly other codes that bypass the lockscreen, soon. You can view the video to see the exact key-sequence.
