QuoteHackers can access iPhones running iOS 6.x without passcodes, and will then be able to access and export the address book, send emails and make phone calls.
Jailbreak Nation has discovered the method for doing so and The Reg can confirm the method works after a sequence of swipes and key presses. It worked for us on an iPhone 5 running iOS 6.02, not just iOS 6.1
There's a nice video on the web page about it too!
Anyone for a 'cup-a-tea-now'?
