Ok, they’re probably going to need to fix this.
Per The Verge, a security flaw in Apple’s iOS 6.1 lets anyone bypass your iPhone password lock and access your phone app, view or modify contacts, check your voicemail, and look through your photos (by attempting to add a photo to a contact).
The method, as detailed by YouTube user videosdebarraquito, involves making (and immediately canceling) an emergency call and holding down the power button twice. Tests confirmed that the hack worked on two UK iPhone 5s running iOS 6.1 and can be seen below:
Similar instances had occurred – and were patched – in iOS 4.1, and was fixed in iOS 4.2.
Apple has yet to reply to requests for comment regarding this situation.
