For those of you who don’t know, iPhone Dev-Team’s Redsn0w 0.9.7 can already jailbreak iOS 4.2.1 untethered but it has its share of limitations. Redsn0w 0.9.7 untethered jailbreak required SHSH blobs of 4.2b3 saved on Cydia. If you don’t have those SHSH files, you cant get the untethered jailbreak.
But if this new video of Chronic Dev Team is anything to go by, an untetheredjailbreak for iOS 4.2.1 is coming real soon.
Stay tuned as we will inform you as soon as it is available for download.
