Apple just issued iPhone/iPod Touch OS 3.1.3, available on your iTunes right away, offering bug fixes to some of the few problems users were moaning about like improved battery level indicator, or third-party applications that failed to launch in some of the occasions. Other issues this update resolves include a Japanese Kana keyboard fix and security breaches related to CoreAudio, ImageIO, Recovery Mode and WebKit.
Update: And those of you, Mac OS X users, who’ve been patiently waiting for a hack ‘n crack to go out, it appears like Dev-Team‘s new Pwnage jailbreaking tool is now officially up and ready to grab. As usual, proceed with caution.
