UnTethered Jailbreak Iphone 4S on iOS 5.0 / 5.0.1 / 5.0.2 / 5.1 Possibility – How to Jailbreak iPhone 4S ? This is the first question that logically asked after you get the newly iPhone 4S in you hands. Apple announced iPhone 4S for the first time on its famous “Let’s Talk iPhone” event in October. So it’s important to explain the situation of iPhone 4S jailbreak in details for our readers so that everyone can take his proper decision.

iPhone 4S / iPad 2 Jailbreak Released Here

 

Can I jailbreak iPhone 4S with the current jailbreak tool ?

To answer this question you have to know that we separated iDevices in to two categories based on its processor’s chip. The first category included (iPhone 4, 3GS, iPod Touch 4G, 3G and iPad 1) which have a less than A5 processor. The second category included (iPhone 4S and iPad 2).

The first category can be jailbroken easily up to iOS 5 with the current jailbreak tool such as Redsn0w and Sn0wbreeze. In the second category, you have to know that the only exploit found to jailbreak iPad 2 was a userland exploit which took more than 1 year to develop by Comex to build JailbreakMe 3.0, but unfortunately, Apple came simply and patched it on iOS 4.3.4 firmware update after 10 days only.

But we still have good news for you, as the hackers have on their hands more than 5 bootrom exploits to jailbreak A5-devices , the iPhone 4S and iPad 2.

Who are involved in Jailbreak iPhone 4S task ?

The good news is that we have 3 different teams that working on jailbreak iPhone 4S on iOS 5 as well as the iPad 2. Let me show you these teams :

1st Team – Chronic dev-team for Jailbreak iPhone 4S:

This is a great and talented team. They are the guys behind the well-known jailbreak tool, Greenpois0n. P0sixninja has announced at the jailbreaking convention MyGreatFest last month that he have five bootrom exploits on the Apple A5 chip. For who don’t know the bootrom exploit are low-level bootrom exploit. What that means that Apple won’t be able to patch them with simple iOS update. Apple should make hardware update to patch them.

Another awesome part, Jailbreak iPhone 4S / iPad 2 untethered iOS 5 will be userland jailbreak which means that you will be able to jailbreak iPhone 4S / iPad 2 on iOS 5 via Safari browser just like JailbreakMe 3.0. P0sixninja confirmed that the upcoming iPhone 4S jailbreak will be the most amazing jailbreak yet.

2nd Team – Georgehotz (Individual) for Jailbreak iPhone 4S:

We heard that the well-know and the God father of the jailbreak Georgehotz (Geohot) may work on iPhone 4S jailbreak as he has un-released bootrom exploit to jailbreak the A5 Devices. But actually there’s no official word from Hotz so far.

3rd Team – iPhone dev-team for Jailbreak iPhone 4S:

We reported you last month that Comex -the guy behind JailbreakMe 3.0- has announced that iPhone Dev-team will make JailbreakMe 4.0 (But it won’t be on Jailbreakme.com as this domain has been sold). JailbreakMe 4.0 will jailbreak iPhone 4S / iPad 2 on iOS 5.

Jailbreak iPhone 4S – Release time :

Jailbreak iPhone 4S release time not confirmed yet. All the above three groups that involved in jailbreak iPhone 4S didn’t give official word on the release date. It will consume some time to perform tests and modification to be released free of issues and holes. Anyway we will keep you updated with this.

iPhone Dev-team has successfully jailbroke iPhone 4S as MuscleNerd just tweeted about the very preliminary iPhone 4S jailbreak on his Twitter account. He also posted two pictures that shows Cydia running on iPhone 4S on iOS 5.

VERY preliminary 4S JB:http://twitpic.com/76vcp4 http://twitpic.com/76vct2 (Huge missing pieces prevent public release. LOTS of work left)

Along with this good news, there is a bad news too. It is clear from the statement of MuscleNerd that there is still a lot of work left in the jailbreak for 4S that is preventing public release. But it is confirmed that the release of iPhone 4S jailbreak is imminent. Also jailbreaking iPhone 4S on iOS 5 means we have iPad 2 jailbreak as well because both iPad 2 and iPhone 4S has the same bootrom. But for all this, you have to wait as you did for iPad 2 jailbreak on 4.3.3.

Please don’t fall for the scammers that tell you we can bring untethered jailbreak on iOS 5 . They all are scammers. Please stay away from them. When untethered jailbreak for iOS 5, iPhone 4S and iPad 2 becomes official, we will let you know.

Conclusion : iPhone 4S and iPad 2 users will be able to jailbreak iPhone 4S / iPad 2 for lifetime very soon.

Update 1: Pod2g bought an iPhone 4S to continue testing his 5.0.1 untethered jailbreak

 

@Pod2g Hi! I have a 4S in hand (thx). Will work hard on it this weekend.

Update 2: Pod2g has issued an update on the progress of the untethered jailbreak for the iPhone 4S.

Here are the news of the 4S week-end. The untether fails right now because I’m having processor cache issues. I’m close, but I can’t figure out what happens. It certainly has something to do with the Cortex-A9 cache management.

I could sort it out quick, it’s a matter of chance. I’ll report you my progress tomorrow.

Update 3: Pod2g has resolved the cache troubles with the iPhone 4S untethered jailbreak, according to a new progress update.

This is Report:
OK, figured it out, the A5 cache is not a problem anymore. I sorted it out by doing the untether in a single thread and by flushing all the dcache then all the icache in a row at a strategical point of the process. It took me like a hundred of tests to find the key. Hard for the nerves.

For the tech guys, here is a link explaining issues related to self modifying code ( or code patching ) on the ARM platform : http://blogs.arm.com/software-enablemen … ying-code/

Another news : I discussed with @saurik today about the launchd boot process, and he’s found one missing piece of the puzzle I needed to have a perfectly stable jailbreak. He’s definitly one of the best iOS gurus out there. Thank you saurik!

Update 4:pod2g just announced that he is going to focus on only iPad 2 and iPhone 4S untethered jailbreak from now onwards and for iPhone 4, iPhone 3GS and iPod touch he has handed the codes over to Chronic Dev Team.

I read the comments on the blog, and I know that a lot of people are waiting for the A5 jailbreak. Also, I know there are tons of people out there with A4 or even earlier devices who wants the untether now and don’t care about it could be interesting to wait A5 is finished to release or even 5.1, so that we don’t waste an exploit that took me months to find and develop.

I need to focus on A5 and hope I can find a path quick, and I have the feeling that chronic-dev could help me. So, here is what I did:
? I gave all the details to the chronic dev team so that they can finish, test, integrate and release the A4 jb ASAP.
? I’ll put all my energy from now on on the A5

For those waiting for an untethered jailbreak on the iPhone 4, iPhone 3GS, iPod Touch 4G, iPod Touch 3G, and iPad 1, it means you’ll see a release sooner than later.

Pod2g recently demonstrated his jailbreak on the iPhone 4. You can watch that here.

As usual we will keep you up to date with the latest

Update 5:  UnTetherd Jailbreak Iphone 4S Release date Next Week. 

Yes, your read it right. iPhone 4S and iPad 2 untethered jailbreak on 5.0.1 iOS to be released within a week. Pod2g, the well-known iPhone hacker and the guy behind 5.0.1 untethered jailbreak on older devices has announced on his Twitter account that he made a good step today on iPhone 4S and iPad 2 jailbreak and he could expect a release in a week.

I made a step today for the A5. With some luck we could expect a release in a week.

For who don’t now, iPad 2 can be only jailbroken on iOS 4.3.3 with the help of Comex JailbreakMe 3.0, which has been patched on iOS 4.3.4 update, since then, there’s no hacker could jailbreak iPad 2. But iPhone 4S has not been jailbroken ever.

As before, we are expecting that iPhone Dev-team is involved on iPhone 4S and iPad 2 untethered jailbreak on 5.0.1, consequently they would release new version of Redsn0w 0.9.11 b1 to untethered jailbreak iPhone 4S and iPad 2 on 5.0.1.

Update : For who asking to update their iPad 2 or iPhone 4S to iOS 5.0.1 or not ? Pod2g has just answered this question, Pod2g advised iPhone 4S and iPad 2 users to upgrade their devices to iOS 5.0.1 to get untethered jailbreak next week.

How to updated iPhone 4S or iPad 2 to iOS 5.0.1 ? 

Now all you have to do is to download iOS 5.0.1 ipsw file Click Here. Then connect your iPhone 4S / iPad 2 with your PC / Mac and run iTunes then Restore to iOS 5.0.1.

Update 6: UnTethered Jailbreak iPhone 4s / iPad 2 Pod2G Question – Answer

According to @Pod2g blog to answer some questions about the iPhone 4S and iPad 2 untethered jailbreak o iOS 5.0.1 and why MuscleNerd Still have Tetherd Jailbreak iPad 2 until now.

How could pod2g have an untethered 4S and dev teams still haven’t released tools to achieve this at home ?

The exploit I used to inject the untethering files to the 4S relies on having a developer account, and can’t be released publicly.

Q:: Why A4 version of Corona was easier to release ?

Q:: Why don’t you do a tethered jailbreak then ?

pod2g, release this stuff quick, [your insult here], I’ve waited enough now.

Earlier this week, pod2g posted that he had made good progress on the jailbreak for A5 devices and said with some luck we could expect a release in a week

Update 7: All Hackers Help Pod2G to UnTethered Jailbreak iPhone 4S/iPad2

Pod2g has announced that Planetbeing, MuscleNerd, and P0sixninja have joined his effort to release an untethered jailbreak of the iPhone 4S and iPad 2.

@planetbeing, the legendary hacker behind iPhone Linux and lot of jailbreaks has joined the A5 research! The famous @MuscleNerd, the leader of the iPhone Dev Team, who did a lot of tests for Corona and whom integrated it and made it simple in redsn0w is willing to help also. And last, but not least @p0sixninja, the leader of the Chronic Dev Team, and my partner for years on iPhone security research has started to code and fuzz the Apple sandbox.

We now have a dream team to find a path for a public release of the A5 jailbreak. Cross your fingers.

Yesterday, pod2g posted Some Questions and Answers on why the A5 jailbreak had not been released yet. but don’t forget to see UnTetherd Jailbreak Iphone 4 S and iPad 2 Possibility and Release date.

With the help of planetbeing, MuscleNerd, and p0sixninja, pod2g is hoping to find a distributable exploit to remount the system partition read/write and to set Corona files at the correct places.

Update 8: today Today, @MuscleNerd, @Planetbeing, and @P0sixninja. They all teamed up to work on the A5 Untethered Jailbreak for iPhone 4S and iPad 2. The only issue was of sandbox on A5 iDevices. Finally today @MuscleNerd Tweeted that:

props to @saurik for major contributions to the A5 version of @pod2g‘s untether yesterday! (still no ETA, but moving forward)

Later on @Pod2g tweeted that:

@MuscleNerd @saurik And greetings to @planetbeing for the coding + research. Really great stuff to escape from the sandbox.
Pod2g also thanked planetbeing for his help in escaping from the sandbox.

And greetings to @planetbeing for the coding + research. Really great stuff to escape from the sandbox.

Finally the sandbox issues are solved on iPhone 4S and iPad 2. The Untethered Jailbreak is still in testing. They will release the Untethered Jailbreak by this week, as said by @Pod2g previously. We hope that they find out any Bootrom exploit which will make it easy for us to perform a restore and Jailbreak in future.

The team is making a great progress. We can expect the Untethered Jailbreak to debut this week. Before the Untethered Jailbreak is released for iPad 2 and iPhone 4S, update your Device to iOS 5.0.1 before it is too late. The Untethered Jailbreak will come for iOS 5.0.1.

UPDATE:
Pod2g has also addressed the request that the untethered jailbreak be released to developers. He previously revealed that there is a working jailbreak that requires a developer account.

Sorry, we can’t release the A5 for the developers, the exploit used have to be kept secret. I know this is unfair.

Update 9: dream team’ has made more progress on the A5 jailbreak with planetbeing just announcing that they’re out of Apple’s sandbox.

And we’re out of the sandbox with @saurik’s invaluable help! (well, at least there’s a PoC) Turning out more complex than X-Gold 618.

The X-Gold 618 is the baseband platform used in the iPhone 4 and iPad 2 (GSM). The Qualcomm MDM6610 is the baseband chip used in the iPhone 4S, for those wondering. As planetbeing notes, more work was needed to escape sandbox for this jailbreak than was needed to escape the iPhone 4 baseband’s equivalent of a “sandbox”.
Now that the team has been successful in breaking out of Apple’s sandbox (which lets them run unsigned code) they’ll focus their attention on writing the OS X and Windows software that interacts with the device.

Update 10: Jailbreak iPhone 4S Becoming Amazing Jailbreak Yet

Jailbreak iPhone 4S Becoming Amazing Jailbreak Yet. yesterday p0sixninja and Joshua Hill tweeted on Twitter that, the , A5 jailbreak is quickly become the most amazing one yet. That makes we curious about how the A5 jailbreak is becoming a hit amazing.

p0sixninja :

@MuscleNerd I said it was becoming amazing quickly, not that it was getting done quickly

Update 11: iPhone 4S Untethered Jailbreak Progress – Unsigned Code Now Running On Device

:

“MuscleNerd: When it’s done and *fully* tested; be patient  Rush jobs lead to mistakes, which are *very* expensive on A5 right now.

Erik Smets: mistake => unstable => restore => no more JB if signing window is closed. I’d rather wait a few more days/weeks.

MuscleNerd: yep that’s a very good summary of the problem we’re trying to avoid! Hah, awesome to see these concepts+concerns propagate 

planetbeing: Finally got unsigned code running on my 4S with the stuff that will go into the new jailbreak!

planetbeing: I was working on it every second I was awake yesterday. There’s a lot of work that needs to be done. No onesaid it’d be quick.”
