Apple may have to release another fix for its recently released operating system update iOS 6.1 to protect against thieves and hackers.
All any would-be thief or hacker would have to do is hold down the power button and abort an emergency call, and they are in, although it does require precision timing.
A video demonstrating the hack, posted on YouTube by a blogger identifying themselves only as videosdebarraquito, is attracting thousands of views.
This means that, until the flaw is fixed, anyone can view or modify contacts, check the voicemail, send text messages, make FaceTime calls and access photos on a locked iPhone running iOS 6.1.

An Apple spokesperson confirmed to AllThingsD that it is aware of the vulnerability and plans to issue a fix in a future software update, but no timeline for the update was offered.
News of the flaw comes just weeks after it emerged that Apple is planning to improve the security of iPhones and iPads by using image recognition or response to unlock the devices.
The US Patent and Trademark Office recently published a patent application made by Apple in 2011 for a system that would require users to respond to a randomly chosen image to access devices.
The system is aimed at making Apple’s devices more secure and less attractive to thieves by replacing the current passcode with something that is not so easily compromised.
