Yes you read that right! iPhone 4 has been successfully jailbroken only within a few days of launch! It looks like the “userland” jailbreak vulnerability which was used by Spirit jailbreak tool was not all that properly patched by Apple, and hence @planetbeing (of Android port for iPhone fame) and @chpwn has managed to get root access on the device using code of @comex’s userland jailbreak method. @Planetbeing posted about this news on his Twitter account.
[IMPORTANT UPDATE: JailbreakMe 2.0 has been released, which can jailbreak iPhone 4, iPad and iPod touch. Follow our guide posted here to jailbreak iPhone 4 / iPhone 3GS on iOS 4.0.1, and here to jailbreak iPad on iOS 3.2.1, and here to jailbreak iPod touch 3G / 2G on iOS 4. Unlock guide for iPhone 4 can be found here, and for iPhone 3GS here]
Think I’m the first one I know about to get a root shell (and SSH) on iPhone 4, using poor @comex’s code (since he has no iPhone 4)
Musclenerd of iPhone Dev Team then followed in by posting this picture a while ago of Cydia running on high resolution screen of iPhone 4.
Congrats to @comex for another userland JB http://is.gd/d5N6I <– hi-res Cydia via @planetbeing & @chpwn iPhone4s

Since iOS 4.0.1 is rumored to be rolled out as early as this coming Monday, an update to Spirit userland jailbreak tool can only be expected after this firmware update has been released sometime in the next week or so which will jailbreak iPhone 4, along with iPhone 3GS (new bootrom), iPod touch (MC models) and iPod touch 3G.
Oh and one more thing, even though iPhone 4 has been jailbroken, don’t expect it to get carrier unlock soon. This is because iPhone 4 uses a new baseband OS, which will require a complete rewrite for ultrasn0w unlocking tool to work on it.
The DevTeam and others have been checking through the iPhone 4, and have noticed the baseband runs a completely different OS than on previous models. The iPhone 3G and 3G[S] both ran Nucleus OS on the PMB8878 baseband CPU (aka XGold 608), where the iPhone 2G ran the PMB8876 (aka S-Gold 2). iPhone 4 uses the PMB9800, or X-Gold 618 – running a separate OS – ThreadX, an RTOS by ExpressLogic.
So what this means is that an unlock for iPhone 4 wont be out anytime soon. So if you are an International user, you are good to go with unlocked versions of iPhone 4. US iPhone 4 users will have to wait for long before they can use this device on carriers other than AT&T.
UPDATE 1: Well there is now little twist to it, another iPhone hacker named p0sixninja has confirmed that it cant be released in its current shape because it contains some of Apple’s proprietary code.
@i_Enthusiast the jailbreak shown is a more of a stepping stone for us, it can’t be released because it includes some of apples software
And speaking of the release date, @planetbeing has now made it more clear that it wont be out anytime soon.
Don’t want to speak for @comex, but afaik no one has breathed a word about release date and what we have right now is nowhere ready.
So there you go.. they will surely have to clear out Apple’s code before they can release this thing.

We will have to see

This is bull, I would prefer a jailbreak now. Is the iPhone 4 really so difficult to crack that it couldn't just be done again after 4.01? I see no point in waiting, as Monday will come around and Apple could just delay.
(#)
Thanks Dev Team seriously… Cant wait for this to come out hopefully for 3GS also
(#)
YAY any estimate release date?
(#)
U can install cydia on 3gs 3.1.3 new bootrom via spirit through MAC Os
(#)
Well that's good news a step in the right direction!

Apple’s New iPhone 4 Anti-Jailbreaking/Unlocking Security Feature?
* Posted on 06.26.10
* AT&T News, Featured, Wireless News
* 3 Comments
So apparently an Apple employee calling himself Alpha, decided to share with the world some of the things that Apple is doing with the new iPhone 4. We’re not talking about new features for the user, but new roadblocks for jailbreakers and unlockers.
Here’s the quote itself:
As far as Base Bands go it does not matter what baseband you TRY to get on the iPhone cause in the iOS4 there is a line of code we wrote that stands for OAU also known as “Over Air Updates”. How it works is every 7 to 14 days We (Apple) and AT&T send a message to your iPhone that gathers some data from your iPhone without you knowing and we see what is running, baseband and firmware. We then send a following message. “There are optional updates for your iPhone, Would you like to install them now?” two options “Yes” or “Later”. Those are what would would call “OPTIONAL UPDATES” Now there are things called “MANDATORY UPDATES”. They tend to work the same way, grab data from the iPhones sends it to AT&T and us then back to your iPhone with the message, “Your iPhone (name of iphone) must be updated to the current AT&T standards to run”, your only option is to “Accept” Now you can try to work your way around it until you get the second mandatory message again “You must plug iPhone into iTunes and update” If you don’t do this you will then receive no Signal from the network anymore and your iPhone will potentially lock up with no signs of use until you update your iPhone via iTunes. You all agreed to this terms and condition when you installed iTunes 9.2 and then again once you updated to iOS4.
With that being said go ahead try to unlock the iPhone it will only last 14 days max then you will have to break that update for that one week then again and again we currently have 6 months worth of updates for this iOS4. Apple and AT&T now have complete control over their iPhones and what their customers are putting on them without them knowing anything about it. Many of the people I work with don’t agree with this but even in our computers when people call in to Apple Care Support we can see if your iPhone is running a jailbreak and what baseband is currently on the iPhone. We have been instructed to not support any one with these things and possible void your warranty of the iPhone for Breaking a contract Rule.
So basically, he is saying that iOS 4 automatically pings Apple every 7 to 14 days with the baseband and firmware information and if it isn’t up to par it will essentially lock up the phone forcing you to update with iTunes (and lose your jailbreak). Now, I know for a fact that we have a perfectly good jailbreaking solution for the iPhone 3G running iOS 4 and it doesn’t relock so I’m wondering if this anti-jailbreaking solution is already circumvented, or if it just only applies to new iPhone 4′s?
(#)
so jailbreak and kill the pingback by installing firewall from cydia
(#)
just release the jailbreak please!!!!!!
(#)
this is an interesting info. tnx for the post.
(#)
This sucks, i guess those of us on the new bootrom have to either keep ios4 on our 3gs/iphone4 and go legit or go back to 3.1.3, as long as you saved your shsh blobs. I was getting all excited when i read the first paragraph
(#)
I don't get the 'update 2' thing. Does it mean that they cleared out Apple's code or is it just a fancy screenshot?
(#)
One look at the “New” badges gives it away, it's certainly real, but incomplete.
(#)
Using fire to fight fire here… How could Apple's code tie in to this?
(#)
If you open source the code and post it anonymously, wouldn't that get you passed the legal issues? I'm willing to pay someone $50 or more if they just let me see the code. :-/
(#)
ill the new sprit jailbreak my 3gs new bootrom ios4
(#)
jas
(#)
no offense, and mass respect, but why don't they work on the new bootrom jailbreak and bring our bricked iphones back, not these worthless minor jb of the ios. iv been hearing the new bootrom jb is coming soon for a bout a month. and they keep releasing these ios4 jb. so i just have one thing to say. STOP RELEASING USLESS SOFTWARE!
(#)
why would you tell the internets specifically what they did for the exploit, now apple is scrambling to patch this for 4.01
(#)
First comment and we are about 2 weeks from ready, but this is a great step letting us know they have pwned the iOS4 but not the iPhone 4.
(#)
you could jailbreak iphone 3g running the 4.0.. using red snow 0.9.5
(#)
I now have cydia apps running on I0s 4 on my 3GS MC model. I have done it myself.
(#)
Geohot just twittered this: @comex not sure why you wrote I am about to release. like you, I don't even own an iphone 4.
(#)
Does anyone know when will a jailbreak be available for iphone 3gs with a new bootrom using ios4 ?
Thanks.
(#)
when is comeing the userland jailbreak
(#)
A question… once the jailbreak/unlock is out, would one be able to buy the boxed AT&T iPhone from Apple Stores in the US and unlock it for any carrier *before* activating any service with AT&T via itunes?
thanks
(#)
umm, I don't really get it..
so, we (3.1.3, 05.12.01) can JB iOS 4 with Spirit?
can sum1 help me, non-native speaker here..
hehe
(#)
oh, so fast, genius
(#)
how have you done it?
(#)
could u plz share how u managed to get this working
(#)
when is jailbreak for iPhone 4 coming?
(#)
Who cares about the damn Apple code? Just release it!!
(#)
Apple is selling unlocked iphone in UK, france, Japan so can't we download the ipsw from there and install it on our iphone and see if it works. its just a software lock. I don't think apple is using any hardware for this kind of lock. also the iphones sold there need UK or France or Japan sim for activation so it makes sense to buy a sim for there and install the os and see if it works. just a thought.
(#)
can you please realease This For ipod touch 3g(MCmodel)
(#)
This article is not about a 3GS it's about an iPhone 4 and the ability to jailbreak. You are off topic.
(#)
i thought about that 2 i was trying to that but u have to have UK France or Canada IP address so ull iTunes will think that ur fro other country not from here
(#)
Well this article is very confusing and why I am seriously considering abandoning the iphone for an Android phone. There seems to be plenty of articles around saying there is a jailbreak for 3GS phones with new Boot ROM but then the catch is you have to have stored the 3.1.2 keys. I am not sure if this is any good to most who have bought an Apple 3GS as for some time now you cannot buy an iphone 3GS with 3.1.2 with the new boot ROM. So there no solution anytime soon for those with a 3GS, New Boot ROM and 3.1.3 OS. Yet there is a jailbreak for the new iphone4 which has the latest firmware, OS etc. So I guess I need to dispose of my 3.1.3 3GS and buy a new iphone4 to be able to have a root access and ssh on the iphone? If I have this wrong please let me know.
For now I have my 3GS new boot rom, with 3.1.3 jailbroken and do not see any need to upgrade to iOS4. It is just a few more apps and a change in back ground screen we do not really need.
I must take my hat off and applaud all those who contribute so much to the community in jailbreak and unlock software. Apple certainly does not make life easy. It might be time to cut our loses and switch to a more open OS and development environment. There are so many good phones now with access to Android.
(#)
how was u able to do that?
(#)
Its your phone IMEI which is listed in apple activation server which hold info that your phone needs to be locked. nothing to do with firmware or software. SO when ure phone gets activated after firmware retore or update. the activation with server locks the phone.
(#)
Uh, EVERY jailbreak is already breaking the DMCA, and of course the EULA, what does a bit of code matter, and can they even prove it once it's compiled? Just don't release the source??
(#)
Yes please and unteathered
(#)
I have iPhone 3Gs 3.1.3 and I do have SSH and I think root access too.
(#)
MORONS. IT TAKES TIME FOR ANY PROGRAM TO BE MADE, LET ALONE ONE THAT RUNS ON ONE OS AND AFFECTS ANOTHER. Sorry about the caps…my cruise control was on. ._. But as I told the foreigners…you all need to be patient.
(#)
I am more looking for hacktivation + jailbreak for the iphone 4.
(#)
Not true. Library of Congress gives a pass (reviewable every 2-3 years I think) on cell phones for DMCA. Thus, as long as not still under a contractual obligation not to do so (which is separate from DMCA), its legal to jailbreak a cell phone.
(#)
mi no speki engle
(#)
I have ipod touch 2G MC Model with ios4. Any tool to jailbreak it.

Do we still have no idea how long its going to be until the next spirit jailbreak comes out?
Will the new software be able to jailbreak my ipod touch 3rd gen version 4.0?

well it will take some time because were still working on it but it will work for all the apple products… and for your ipod touch 3gen it will work perfectly no questions asked
(#)

(#)
When is the new Jailbreak coming out? Is it a few days, weeks, or months away? I heard rumors that the new version of Itunes as well as this new software update for the reception is going to somehow hack the phones so Apple knows if your phone is jailbroken, is this true? and if so, will people jailbreaking the phones take that into consideration and trick Apple?
(#)
i want to downgrade my 3g 4.0 i pod touch but i can't get by the error 3194 and i have tried lots of sites and they all didn't work. i really want to jailbreak. Can someone please help me???

(#)
I had installed the fresh-0.01.deb version of this, this one mentioned here Is 0.02. I was disappointed with what I had installed – didn't work whenever i wanted it. It made the web pages look ugly before i clicked on it also.
As comex mentions this to be alpha quality now on his github project for fresh, I will wait for this to reach beta quality at least.
PS: I have some good APPS from aneesoft want to recommend. Maybe someone will like it.

Hello all,
My issue that I have Iphone 3Gs already jailbreaked thanks to Spirit, and I have no idea which why should I take to upgrade to OS 4, I'm afraid to lose my jailbreak back, or something wrong could go there…
Any experience or advice?
Chears!
