P0sixninja has revealed that he will not be using his jailbreak exploits to release a jailbreak for iOS 6.1.3; rather, he will be holding them back for iOS 7 or iOS 7.1.
Pod2g, the hacker behind the iOS 5.0 and iOS 5.0.1 untethered jailbreaks, has revealed that a public jailbreak for A5+ iOS 5.1 devices is at minimum weeks away.
Pod2g has asked the jailbreak community to send him any iOS 5.1 crash reports that are reproducible to assist in finding a jailbreak for the new firmware version.
