Jailbreak for iPhone, iPod and iPad released, by GeoHot

As the cat and mouse game between Apple and the jailbreaking community continues, another exploit has been discovered that will jailbreak the iPhone 4, iPod touch 4 and iPad. The exploit was found within the A4 chip bootrom, similar to that of the iPhone 3GS (old bootrom) exploit.

The exploit was discovered by p0sixninja, who originally planned to make the jailbreak available tomorrow, on 10/10/10 at 10:10 AM. The exploit will only work on the iPhone 4, iPod touch 4 and iPad, as they all use the A4 chip, but the team mentions that there will be future releases.

However, once the Greenpois0n team announced their ETA for their release, GeoHot suddenly came out of retirement and announced he will release a jailbreak on 10/11/10. After GeoHot made this announcement, he quickly compiled a jailbreak, using p0sixninja's exploit, and released it ahead of Greenpois0n, which is still slated for tomorrow, at the time of writing.

Limera1n works on the iPhone 3GS, iPod Touch 3G, iPhone 4, iPod touch 4, iPad on iOS 4.0, 4.1 and beyond.

GeoHot, aka George Hotz, is famous for his widely used BlackRa1n, which could jailbreak any Apple device at the time. Hotz was also the first hacker to successfully unlock the first iPhone, allowing it to work on any GSM carrier in the world.

with my version i loaded it with 2g 4.0 and jailbreakme.com but with a first gen upgraded 2 lastest firmware 3.13 and jailbreakme.com but my ipad limern did the job

if your 3G was already jailbroken, and you made a copy of your SHSH, then just download TinyUmbrella, download the 4.0 firmware for your 3G device, start TinyUmbrella, open iTunes, SHIFT+Restore, find your 4.0 firmware and there you go.

Once you jailbreak 4.1 on the NEW iPod Touch, iPhone then you're good. If you have a 3GS I believe it can be patched. But, say someone upgrades to 4.1.1, they can still jailbreak but it'll be tethered, so every time they reboot their phone they'll need it to be plugged into the computer.

The jailbreak is unpatchable, but the untethered part will be patched in Apple's next firmware, meaning everything you restart, you need to be connected to a computer to keep the jailbreak. But, like I said it is unpatchable.

Limera1n seems to work fine for me. He left the scene already knowing of an exploit that Apple didn't patch, and decided to release it due to Chronic Dev Team having an unpatchable exploit due to an exploit in the hardware. So, he released his exploit to save the CDT's exploit. It was for the best. And as to 'why jailbreak?', because there are some good Cydia applications that Apple don't approve. Like facebreak or 3G Unrestrictor that lets you use programs on 3G that depend on WiFi to use, such as Facetime. I don't want to have to be on a WiFi network in order to see my wife when the military sends me off to other states.

I discovered something interesting. My 3G iPod Touch has the 2G firmware on it, and when I try to manually update it with the proper 3G firmware, it says it's not compatible.

Anybody know why this would happen? Unless some 2G iTouch's have the MC model type.

What firmware version are you trying to update to? Because you can get 4.1 if you would like.

So it's actually a 2G iPod Touch then?

hey what am i doing wrong plz help

You're not doing anything wrong. You, me, and a ton of other people can't get it to work on the Touch, so it looks to be that there are some bugs that have to be worked out.

I haven't attempted an install of this exploit. Probably wait a few days to see if anyone has any major issues with it. The Twitter trash talk between the hacker groups is amusing. It looms like we won't see greenpo1son today, as they say they are saving their exploit and just using the one released gy geohot.

I think this news is wrong... or maybe I missed something somewhere. Geohot's limera1n doesn't use p0sixninja's SHAtter exploit. He used his own exploit.

Thanks to GeoHot for limera1n and respect to DevTeam for swallowing their pride - the sign of a true gentleman - and deciding to withhold their SHAtter exploit for iOS 4.2 (http://twitter.com/p0sixninja)

ok ive tryed this thing on 3g i touch and i dont see an icon what am i doing wrong

Same here. I don't think it works or has even been tested, so we might be S.O.L for now.

I'm using it on my iPod Touch 3G. I can confirm that it works so it's got to be something you're doing wrong. Simple steps really.

- Upgrade to official 4.1 firmware
- Run Limera1n
- Once jailbroken, run the installed Limera1n app and install Cydia from within (be sure to have a WiFi connection working to get the Cydia bit to show up)
- Sorted.

How'd you manage that? You're the first person I've heard of on the iTouch 3G to get it working. I've retried many times following all the steps exactly, and still no Cydia icon.

Astra.Xtreme said,
How do I install Cydia now? I think the jailbreak worked, but I expected it to be auto installed.

on the springboard, tap the Limera1n icon. you'll download/install Cydia from there

you can also uninstall Limera1n as it's really only needed once

timster said,

Well it looks like it's not working on the iPod Touch 3G then. I've restored a few times and re-jailbroke it a couple times, and I don't have a Limera1n icon ever show up. Any ideas?

I think we should wait for greenpoison to release their version, it was a long wait....might aswell wait a few more days and choose which is best

Geohot actually used another exploit, not the one discovered by pod2g.
He did use comex's userland thing to make it untethered, though.
It was also in the works for a few months beforehand.

Lots of drama with this one lol. I'll hold off a few days a see what comes out on top.

Holy crap, you're right! Turning off wallpaper makes my iPhone 4 even faster
Thanks. If you have any other suggestions, keep it coming!

Airplane mode, disable all services, uninstall everything - or better yet, don't use it for anything trivial or non-trivial.

Turning of a wallpaper shouldn't be a speed-increase...

Do you even have an iPhone?
And yes, I don't know if it "shouldn't be a speed increase". I don't know why, I don't know how, but the fact is that it's clear to me THERE IS a speed increase, hmkay?
Troll.

Disabling the backgroup wallpaper was an accepted "speedup" in Windows 95 - in 2010 you should really not notice a difference from just changing the background - even if it's a phone in comparison.

Just jb'ed, even though I couldn't care less about themes or pirated apps. Besides that, anybody got suggestions? Thank YOU!!!!!

SBSettings (Free), zToggle (Free), Iconoclasm (Paid), Infinifolders (Paid)

Seriously try zToggle and turn multitasking and wallpaper off, HUGE boost in performance!

I find Backgrounder useful for apps that don't support the multitasking framework. LockScreen Info (Paid) was kinda cool for reading new emails from my lock screen. MyFi 4.0 (paid) is good for free tethering over WiFi (although probably goes against the terms with your carrier).

Bricked my iPhone 3G. Restoring from iTunes now... luckily I did a backup beforehand.

does it support iPhone 3g. I did not see it in the description.

If you are restoring via iTunes, then your phone ain't THAT bricked. Careful how you use that word. People read that and think that your phone is permanently broken (i.e., as good as a brick).

This doesn't jailbreak the iPad though, because the iPad is currently only at version 3.2.2 which this only works for versions 4.0 and up....

This is the hardware exploit that cant be "fixed" by apple via software update.

Confirmed working on my iPhone 4. Reboot after installing cydia through limera1n (it'll force quit)

As per above comment, I bought apps from cydia to enhance functionality of my phone. Not everyone wants to pirate, and jailbreaking is legal.

And this is "news" why? Why is this site continually supporting those who make it possible to circumvent Apple's control of their own product? The only reason these people use these exploits is so they can pirate apps that people are selling on the app store. And yet again, Neowin.net is right there advertising for them.

It's more about giving USERS more control over the product they bought, and less about making Apple lose its control.
Also, these exploits allow some people to later on install a baseband unlock in order to use their non-sim-free iPhone w/ a 3rd party carrier. Again... freedom for users.

I jailbroke my iPhone 4 and I haven't pirated an app, and I don't plan on it either, I just wanted a different theme.

The software is Apple's product. The hardware is property of the user. Why shouldn't they be allowed to use their hardware as they wish.

It's legal to jailbreak phones. So its okkkkkk.

I jail broke my iPhone and ended up BUYING $24 worth of non-App Store apps (LockScreen Info, MyFi).

Jailbreaking devices is now legal in the USA, so these articles are perfectly valid.

Neowin.net advertising seem's to have worked!!!!...Got you thinking hard enough to post a comment!!!...Not All Jail-Break user's arrrr pirate's!!!!...Beside's it is a Apple product, you right there!!...but i OWN it!!!...So it's mine to do what (should be able out of the box) ever i want it to!!!...A door stop,base ball or even a phone!!!

Sigh. Most people who jailbreak do not pirate apps.

Welcome to the "scene". Hacker ethics and all, it all comes in second priority to being first. Greenpois0n were naive when they boldly announced their release date. Hackers are also common people, not only glorified mysterious elite programmers.

morphen said,

The people who download geohots tool and cry when it doesn't work because he does no real testing (Disclaimer, I am not one of those...)

He's also wasted a different exploit that the dev team knew about, but didn't want to use for this release. They trusted him not to use it. Now they are forced to rewrite their code to use that exploit, rather than use a different one than him and have Apple patch two exploits, at least that's what I can work out from the twitter messages >.>

From what I've seen, this is completely true.

what do you expect when it's free? and I BET i comes with a disclaimer saying somthing like "don't blame me if it does not work".

TechDudeGeorge said,
But from multiple reports on twitter, limera1n is very unstable and does not work as well as the upcoming Greenpois0n

It wouldn't surprise me, he rushes it out with little testing just to be "first"

What is the point of jailbreaking anyway? ok you can download anything you want until Apple patch it again and you will not be able to upgrade the OS. Jailbreaking to me is like hackintosh your PC, works great with tools that you need, but then Apple deliver an update, bam! your hackintosh does not boot anymore or if you don't install the update you leave a system unpatched. Jailbreaking is not for me.

You should try Android - where you get the positive effects of jailbreaking - without jailbreaking it.

And yet why are there custom ROMs for Android phones? Jailbreaking and unlocking happens on every platform and phone these days. There will always be people who want to customize their device beyond what it comes with. The iPhone is not the only device that this happens to and Apple is not the only company that tries to prevent it.

Well, Google is not the company that tries to prevent it - and custom ROM's are for those who take it a step further - the phone is fully functional without it.
And by fully functional I mean you have proper multitasking, can change any theme you want etc.
Some of the stuff Apple has prevented you from doing.

The iPhone has multitasking now. Lets bring a new argument. So this is all about themes? I won't say that it's a silly reason to jailbreak your phone. Its just not that big of a deal to me. But to each their own. What other "fully functional" things does Android have that the iPhone doesn't?

Not just about themes.
Jailbraking allows you to get some very useful features for your phone.
Quick reply from the lock screen, a proper notification system, emulation of older platforms, being able to tidy up the multitasking bar, etc.

Android enthusiast really never have an answer to that. They like to say that their phone has more functionality without giving any specific examples. Meanwhile Android manufacturers are making more advances at locking down the platform rather than providing new and useful features. About the only thing I've seen from non-unlocked Android is WiFi tethering (that you still have to pay extra for if you use it). I have to use Bluetooth or a cable and pay extra on a non-JB iPhone. JB/root gives you this feature for free (although against your providers TOS).

Also, Android has Flash which is useful and something iPhone should have.

Yeah I always hear themes and multitasking but now they only have themes. I'm all for Flash as long as it can be disabled completely in the settings. I've seen it in action on Android and its poor to say the least.

Those all sound like pretty weak features. There's a reason the lock screen is there. I've used jailbroken apps that can be used from the lock screen. Kinda just leaves your data out in the open if someone gets it. And how does the iPhone not have a proper notification system? And what would the need be to use a newer device on a newer platform to run old software? Don't really understand that but whatever. And I thought you can tidy up the multitasking bar on an iPhone. At least I can on mine. So all I've really gotten from you so far is themes. Got it.
