The iPhone Dev-Team has made an announcement today on twitter that successful untethered jailbreak for iOS 4.2.1 on all devices has been achieved. However, this would be beneficial only for those who have their 4.2b3 SHSH blobs backed up. In case you don’t have these blobs saved up, don’t worry coz according to @MuscleNerd, its just a backup plan as @comex is already working on a permanent solution for everyone!
@MuscleNerd wrote the following tweets:
“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”
Stat tuned and we’ll keep you posted as soon as it becomes available for public download. Meanwhile, check out the untethered 4.2.1 jailbreak in action in the following video:
