An article in techcrunch.com revealed that with a simple workaround, a person can open the phone app on any locked iPhone running iOS 6.1. From there a person has full access to the photo library, can edit contacts, and send emails, text messages or even make a FaceTime call.
Apple is aware of this bug. While waiting for the fix, users must take precaution and not simply leave the iPhone around. I definitely do not want my photos in my photo library to be viewed by others, or letting others have chance to send prank message to people in my contact list.
