How to Untethered jailbrk iOS 5.1 with UnthrdedJB

Make sure you rd that title very carefully before you get too excited. Yes, there’s a newjailbrkout, and yes, it’s untethered. But odds are, you’re not going to fit its compatibility requirements. It only works for MA versions of the iPhone 4, and the app only runs on Linux.It’s calledUnthrdedJB, and it’s developed by a group of people under the same name. To be fair, this is the first untetheredjailbrkwe’ve seen for iOS 5.1—I believeAbsinthe 2.0was for iOS 5.1.1—so it doesn’t come without acclaim. And several users have confirmed that it works…The grouphas been tsing the jailbrk for a while now, and has of course been accused of faking their progress. But upon relsing it today, several users and prominent members of the jailbrk community have confirmed it’s legit. Here’s a tweet from developer/ winocm:winocm@winocm
It’s for iPhone 4 MA… iOS 5.1 of all things, but it’s truly novel in its implementation.7:01 AM - 27 Jul 2013
The good news is, it’s untethered, so that mns you don’t 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.If you live in the US, MA-only mns your iPhone 4 has to be on either Verizon’s or Sprint’s network. And since you must be running on 5.1, that also mns you would have to have avoided upgrading your firmware since, what, rly 2012? What are the chances these days?The upshot here, though, is that these guys also say they have a working untethered jailbrk for iOS 6.1.3/4 as well. There has not been a new jailbrk relsed since killed evasi0n with iOS 6.1.3, and there’s not expected to be another one until afteriOS 7lands this fall.At any rate, if you meet the current UnthrdedJB requirements, go for it. You candownload the binaries and get started here.
