A new untethered jailbreak could be released shortly after the major update to iOS 6 is released in the form of iOS 6.1 (via CultofMac). According to the report, a number of hackers are waiting until iOS 6.1 is released to determine whether the vulnerabilities that will be used in the successful jailbreak process are fixed by Apple. Should any of the jailbreak access points remain open after the release of iOS 6.1, then it is likely that a full untethered jailbreak will be unleashed shortly after the release of iOS 6.1.
There is no official word on when either iOS 6.1 will be released but according to the report, the current developer beta of iOS 6.1 will expire on January 28, so Apple is expected either to release a further beta to developers, or the final Gold Master (GM) version. If indeed the GM version is released then it would only be a matter of days, rather than months, until the GM is released to the public after final testing. The jailbreak would then, presumably, follow shortly after, assuming that it still feasible.
The team responsible for the jailbreak is using the novel name of ‘evad3rs’ and is comprised of some well-known jailbreak names such as pod2g and MuscleNerd.
