Apple: Whoops, they did it again

A security flaw in Apple's operating system could give hackers access to users' phones.

A bug in iOS 6.1 lets anyone bypass the password lock on the device. The hacker would be able to make calls, listen to your messages and access the contact list.

Similar bugs have been pointed out in previous versions of Apple's mobile operating system. The company usually acts quickly to issue updates to fix problems.
