The new untethered jailbreak called “UnthreadedJB” and it’s developed by a group of people under the same name. To be fair, this is the first untethered jailbreak we’ve seen for iOS 5.1—I believe Absinthe 2.0was for iOS 5.1.1—so it doesn’t come without acclaim. And several users have confirmed that it works…
“UnthreadedJB” hackers group has been testing the program in the past few weeks and has of course been accused of faking their progress. But upon releasing it today, several users and prominent members of the jailbreak community have confirmed it’s legit. Here’s a tweet from developer/hacker winocm:
So right now CDMA iPhone 4 users will be able to enjoy using the new untethered jailbreak, which means you will not have to worry about hooking your device up to a computer after every reboot. The bad news is, it requires that you meet a very narrow set of standards. You have to have a native Linux computer, and an iPhone 4 on iOS 5.1.
The upshot here, though, is that these guys also say they have a working untethered jailbreak for iOS 6.1.3/4 as well. There has not been a new jailbreak released since Apple killed evasi0n with iOS 6.1.3, and there’s not expected to be another one until after iOS 7 lands this fall.
