The first beta of iOS 6 has only been in the wild a few days but has already been jailbroken in the developer’s mode. The Dev team released a dev build of Redsn0w 0.9.13 to handle the jailbreak which works on iPhone 4, iPhone 3GS, and iPod touch 4G, though each device is tethered for the time being and there are a handful of major issues with the jailbreak that should prevent most users from attempting to use it on their devices. The major issue with it is the ipsw file of iOS 6 which is still the developer’s ipsw and cannot be handled by most of the people. The general users are still stuck up on iOS 5.1.1 and will be able to download iOS 6 at a later stage but for now the users should stick to iOS 5.1.1 and not try the developer’s iOS 6 because it is way too dangerous to try ones hands on it.
As the version implies, Redsn0w 0.9.13dev is intended for developers only. There are many components that do not work, including Apple’s default apps, many 3rd party apps, Cydia apps, and more. Adding on, this version of the tethered jailbreak does not install Cydia on to the homescreen which again is a MAJOR issue for users to deal with currently. Because of all these cavities this is really a proof of concept and should not be widely adopted beyond those developing jailbreak tweaks or apps, but it does suggest that when iOS 6 is released to the public a jailbreak will accompany it rather quickly.
If you’re a developer and you wish to try this out, point Redsn0w at the iOS 6 IPSW file to jailbreak, and then boot tethered. As the Dev Team mentions, anyone attempting to use this version of redsn0w will need a registered UDID to activate their device.
iOS 6 is scheduled for a public release this fall so we recommend the naive users to stay away from it and enjoy the perks of iOS 5.1.1 with a successful untethered jailbreak using absinthe.
