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:
Last week we reported that the well-known hacker Geohot might call his next jailbreak tool rubyra1n. Now guts from Dev Team hit that they know something about Geohot’s effort to bring a proper untethered jailbreak to iOS 4.2.1.
A recent tweet from MuscleNerd confirms the rumors: “I hear geohot does have an untether actually! Though not for all devices”.
The iPhone Dev team has just released the second beta of their untethered RedSn0w jailbreak (the first beta has been released few hours ago and has more bugs).
New jailbreak is called “Jailbreak Monte”, as it uses new “backup method”. The iPhone Dev Team warns that their beta-version is not a general release and you should back up all your media before using it. There are also other limitations and bugs:
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.
Currently iOS 4.2.1 jailbreak for , iPhone 3GS new bootrom, iPad, iPod 3G/4G is a tethered jailbreak. That means if you have to reboot your device, it will show a “connect to itunes” logo until you run the jailbreak software again. Musclenerd from iPhone DevTeam has announced that untethered jailbreak for iPhone iOS 4.2.1 is ready. Unfortunately this will be only for those who saved 4.2b3 SHSH keys via Cydia or tinyumbrella.
Got “backup plan” for untethered 4.2.1 JB working (video coming up). Uses mysterious 4.2b3 hashes Cydia kept for you.
“Backup plan” because hacker comex is working on a more extensible jailbreak. We’ll keep you up to date with more information as it develops. For now you can watch the proof video:
UPDATE: Please think first, before you do something.
UPDATE2: If you have 05.13 baseband or lower – do not update to 4.2.1, use PwnageTool to create custom firmware!
This is step-by-step instructions on how to jailbreak and unlock your iPhone 3GS on iOS 4.2.1 firmware using RedSn0w 0.9.6b5 for Windows.
For iPhone 3G use .
If you have an iPhone 3GS with the new bootrom you will only be able to perform a tethered jailbreak at this time. This means you will need Redsn0w’s assistance to boot into your jailbroken device.
IMPORTANT FOR UNLOCKERS
During this process you can update your baseband to the 06.15 version. If you are on 05.14 or 05.15 or higher you will need to do this to unlock. You do not need to do this for jailbreak only. Please read the following very carefully before deciding whether to do this.
DevTeam worked hard for the last several hours and released jailbreak tool for iOS 4.2.1. It is redsn0w 0.9.6 b4.
As usual we remind all ultrasn0w unlockers please stay away from this official firmware. Wait for the ability to create custom 4.2.1 IPSWs that don’t update your baseband!
New redsn0w 0.9.6 b4 uses limera1n exploit and will successfully jailbreak all devices. The only problem is that it is a tethered jailbreak, which means you will have to plug it to a computer and rerun redsn0w on every reboot. This so called tethered or semi-tethered jailbreak. This condition applies to iPhone 3GS (new bootrom), , iPad, iPod touch 2G (MC model), iPod touch 3G and iPod touch 4G. Hackers are working hard to create untethered jailbreak for these devices. To use future untethered jailbreak you need to save SHSH keys for iOS 4.1 using utility or directly in Cydia.
Old devices like iPhone 3GS (old bootrom), iPhone 3G and iPod touch 2G (non-MC model) can be jailbroken-untethered right now using this latest version of RedSn0w.
You can download RedSn0w 0.9.6 b4 .
Next iPhone/iPod/iPad firmare iOS 4.2 is due out soon. What can we expect in terms of jailbreaking 4.2?
Limera1n exploit for 4.2 in most cases is a tethered jailbreak. That means if you have to reboot your device, it will show a “connect to itunes” logo until you run the jailbreak software again.
- iPhone 3G – will run 4.2 untethered. Redsn0w will be updated.
- iPhone 3GS – old bootrom will run 4.2 untethered if done via Pwnagetool while updating from 4.1. Otherwise it will be tethered.
- – tethered
- iPod 2G – untethered.
- iPod Touch 3G, iPod Touch 4G – tethered
- iPad – tethered.
Tethered jailbreak isn’t that bad for iPads and iPods. But if something happens and your iphone reboots while you’re away from your computer, you cant use the device until you get home and run some tool on your computer again.
We suggest not updating until new expoit will be implemented in new utility.
The community is working on a solution to this to either make the jailbreak untethered or at least semi-tethered. Semi-tethered means the device will at least reboot, but unjailbroken while on the road until you return to your computer.
The Chronic Dev-Team has released RC4 of their Greenpois0n jailbreak utility which brings support for the iPod touch 2G.
Greenpois0n RC4 posted on www.greenpois0n.com – support for iPod Touch 2G, MC and MB, both untethered.
You can download Greenpois0n RC4 .
