Apple today launched iOS version 6.1.3 for iPhone, iPad, and iPod Touch users.

The latest update fixes a security flaw that allowed someone to gain access to an iPhone by getting past the lock screen.

By following a specific series of steps, including making an emergency call, a person could get around the passcode and make phone calls, listen to voice mail, or check contact photos.

iOS 6.1.3 also adds improvements to Apple's Maps app for users in Japan.

iOS users can update their devices over the air by opening the Settings screen, tapping on General, choosing Software Update, and then downloading and installing the latest version directly.
