Good news everyone. DevTeam recently posted a tweet where they inform us that they will soon release a new version of Redsn0w utility for Windows. It will be an untethered jailbreak for iOS 4.2.1 using the Monte iOS 4.1 technique.
In fact, Apple still provides 4.1 ipsw and this could be used to jailbreak.
In addition, the team warns that Windows version will be very slow because the program uses the filesystem instead of RAM.
The Chronic Dev-Team has announced via twitter an untethered jailbreak for iOS 4.2.1. This should work for iPhone 3GS (new bootrom), and iPad. And it will not require saved iOS 4.2b3 SHSH keys.
The untether is demoed in the video below. It’s a result of a collaboration between @0naj, @p0sixninja, and @pod2g. P0sixninja has previously said it will not require iOS 4.2b3 SHSH blobs.
A small bug with wifi still remains. They will release utility as soon as they fix it.
Here is a video proof:
MuscleNerd from iPhone DevTeam tweeted that an untethered jailbreak solution for iOS 4.2.1 will be released soon, probably next week.
scotty6kids78: @MuscleNerd are we any closer to the unteathered #jailbreak for the new #ios4.2 on #iphone4 ?
MuscleNerd: @scotty6kids78 it’ll be here by Xmas (not because we’re sitting waiting for Xmas, but because it’s achievable deadline)
This untethered solution will be applicable to all current iOS 4.2.1 devices, including , iPhone 3GS, iPad, Apple TV 2G and iPod touch 4G. We will keep you updated.
