Musclenerd just posted a video on YouTube, showing an iPod touch 4 running on iOS 4.2.1 with untethered jailbreak. Apparently iPhone Dev team managed to exploit a hole they found in iOS 4.2 beta 3.
As usual no ETA, release date from Dev – Team side is available at the moment. We’ll update this page as soon as we get some you information or progress report. Stay tuned with us.
Got “backup plan” for untethered 4.2.1 JB working (video coming up). Uses mysterious 4.2b3 hashes Cydia kept for you
(It’s a “backup plan” because comex is working on a more extensible one, but this method is also generalizable)
ipt4g 4.2.1 untethered JB w/4.2b3 kernel: http://is.gd/inE4e … Wastes no exploits, but upcoming @comex JB maybe better
Check the teaser video after the break 😉
