Apple releases iOS 6.1.3 to patch lock screen security hole
 

A month to the day after Apple issued iOS 6.1.2 in order to patch an Exchange bug, the company has pushed out iOS 6.1.3 today to seal up a security hole that allowed a complex combination of finagling to bypass one's lock screen. Moreover, it's said to add Maps updates for the nation of Japan, while also adding a variety of undisclosed "security patches." It looks as if all modern iOS devices (iPad and iPod touch included) are eligible, so feel free to hit up the Settings menu on your device or plug it into iTunes. If you aren't seeing it right away (as is the case with this particular editor's iPhone 4S), just keep trying. And trying. And trying.
