Apple recently released iOS 6.1.3 which fixed a lock screen vulnerability; however, it turns out there is yet another one to be fixed.

As demonstrated in the video below, it's possible to get access to the Contacts app and then other areas of the phone including photos by using Voice Dial then ejecting the SIM card.

Sorry, iOS 6.1.3 has a new security flaw, but can be avoided easily. You should disable the "Voice Dial" option if you want to be safe.

Take a look...
