Breaking News: iPhone 4 Already Jailbroken

Jailbreak iPhone 4

It didn’t take that long. iPhone 4 that was officially launched earlier this week has been successfully jailbroken.

Comex, developer of popular jailbreaking tool, Spirit jailbreak for iPhone OS 3.1.3, iPhone OS 3.1.2 has discovered another userland jailbreak in iOS 4 similar to the one used in Spirit jailbreak.

iPhone hacking experts planetbeing, chpwn and MuscleNerd of the iPhone Dev Team have managed to get root access on iPhone 4 using comex’s userland jailbreak.

planetbeing was the first to announce the breaking news on Twitter:

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 has confirmed the news and has followed it up with a screenshot of Cydia running on iPhone 4:

Congrats to @comex for another userland JB <– hi-res Cydia via @planetbeing & @chpwn iPhone4s

Jailbreak iPhone 4

The discovery of the new exploit in iOS 4 should also be great news for iPhone 3GS and iPod Touch (MC version) users with the new bootrom as the tools will jailbreak them as well.

However, this does not mean that iPhone 4 can also be unlocked. iPhone 4 comes with a new baseband, which will require Ultrasn0w to be completely rewritten to work on iPhone 4.


MuscleNerd of the iPhone Dev Team has published the screenshot of full root access on iPhone 4, which is possible only if it is jailbroken:

Jailbreak iPhone 4

Thanks Jasmart for the tip!

  • Wolverinemarky

    lol well done dev team hopefully will be release by the time o get my white iPhone


    It should be out by the end of the week…

  • Keebs357

    First create Custom IPSW with snowbreeze on 0s4,For 3GS with old bootrom 6.4, MC135ll, 4.0 os, If you did the cydia save with shsh. Downgrade to 3.12- jailbreak with blackra1n, go through the activation with itunes 9.2. then hit shift And restore and look for custom 4.0 os snowbreeze IPSW. Forget about if you used spirit. Your phone will jailbreak with no 1600 Error.
    I did mine like that and then added Ultrasn0w. Keebs357

  • Mac

    By da way im just makin up a theory. Plz dnt say crap to me.

  • Mac

    Also i thought devs would take longer like maybe a week or two. GRET JOB TEAM! I thought GeoHot would release the rumoured limera1n. Yeah….. Icnt wait for this jailbreak cuz da other two jailbreak look complicaited


    when can i jailbreak my iphone 4g i just got it june 24th

  • 3.1.2GS

    Well i hope it isn't released too soon – cos Apple may be looking to release a firmware upgrade to fix some issue's that you may have heard about?
    Would be bad too lose an exploit so soon 🙁

  • Fingers

    You really didn't get an iPhone 4g!!! Maybe an iPhone 4??? The only reason I have left to jailbreak is customised SMS tones, cos the factory ones suck. Sort this apple and I reckon you've pretty much cracked it for me!

  • Juris

    Can somebody please tell me, when it will be possible to hacktivate iphone 3gs MC version, 3.1.3 05.12.01, 6.4, new bootrom?

  • yashif

    i have a 3g running in 3.1.2, baseband 05.12.01, model MB046ll. can i update the firmware to iOS4, baseband 05.13.XX and jailbreak it and use ultrasn0w to unlock it.. 🙂

  • Vahan


  • Vahan

    Btw, you have to update with the custom FM not official update

  • endri

    this is excellent!!!!

  • endri

    geohot is in vacation so you shouldnt expect anything from him!!!

  • HotzSucx

    Geohot is a lazy twat so you shouldnt expect anything from him!!!

  • HI5

    it mins if we r stuck on itunes logo connect i tunes we can upgarde

  • Ohhhhh man where is this for the 3gs guys, come on dev team your letting me down, keep up the good work tho

  • Theahbal

    Damn I just saw a posting that this is no where near ready because the exploit uses apple software! I was really hoping to free my I4 but i guess i might have to go back to my 3Gs for the mean time!

  • خبر جميل جدا.

    لكن متى يكون متاح للأشخاص ؟

    i have 3gs ios4 (new bootrom) its there a jailbeak for it ??

    thank U guys

  • Lavender

    Hey iphonehacks,
    I'm just asking for a little clarification please: you've said that this iphone 4 jailbreak method won't unlock iphone 4 – but doesn't UltraSn0w 0.9.3 unlock all basebands included with iphone OS 3.0 all the way up to iOS 4.0 ??? Or does it only unlock previous iphones running iOS 4.0? Please clarify!
    Thanks in advance!

  • Mac

    Yeah thts what ive heard

  • Mac

    No. This jailbreak is for all models (including new bootroms)

  • Saj

    I think this is great news that these guys have find a way in iPhone 4 iOS4 but since a lot of us (including me) are having issues with the signal problems and apple has comfirmed that they'll be releasing an update soon,… Is it not a good idea to wait until the update is out first and then release the Jailbreak??? Apology if causing any problem.

  • Go England!

    What baseband does the iPhone 4 come with ?

  • Benji

    Why is everyone thanking the Dev team for this? Its not them, they just confirmed it working etc. Comex (creator of the Spirit jailbreak) found the exploit and created the hack.

  • Charles

    Anyone else think that screen shot looks more like an iPad screenshot, with the rotation lock symbol in the top right hand corner?

  • brittosa

    iPhone 4's 05.13.04 Baseband is definitely Unlockable… the only problem is its running a different real-time OS (ThreadX) than that of <3GS (Nucleus OS). So, DevTeam and the others are trying to crack through this nut right now.

  • smash

    This is about iphone 4.

  • hxclos

    The article clearly states Ultrasn0w has to be rewritten because the iPhone 4 has a new baseband.

  • hxclos

    The rotation lock was included in iOS 4. Looks to narrow to be an iPad

  • I feel we should wait for few more days as Apple is going to Update iOS 4.01, most probably Apple might block the port (Hole) with update.

  • just sayin'

    did u buy that iphone brand new? or did u buy it from someone else who had at&t service? i'm assuming that u want to use it for another carrier other than at&t. if its the case where u bought it from another user, it may have already been activated and registered at some point. in that case, u can insert an at&t sim card (if u have access to one) into the iphone, and it will activate itself through itunes.

    once it's activated, you can use Spirit to jailbreak your iPhone 3GS on 3.1.3

  • Keebs357

    No for 3GS that were updated to os4 with 5.13, old bootrom, and now can't restore and get message error. And can't jailbreak. This is how I was able to do it.

  • danny

    so does this mean that we shouldnt update the firmware to 4.0.1 when it comes out? cause that wont be able to be jailbroken yet

  • iritated

    Talk normal, this is not text! how old are you?
    when you type like people used to text, you sound stupid, or young!!!

  • Alejandro

    I have a lil problem… I upgrade to 4.0 but I use spirt before… N now I can't jailbreak my phone does anyone has an idea how to do it…. N I have an iPhone 3GS…

  • No Te Meta

    Downgrade to 3.1.3 and jailbreak

  • yashif

    can anyone reply me??? 🙂

  • yashif

    i used sprint to jailbreak my iphone, so does it jailbreak after i update to iOS4 ?

  • Divxclub

    So … Looks like Iphone 4 Jailbreak is now a reality. IS it public yet ? Thx !

  • Mac

    Im on iphone and the keyboard is all small and stuff. There!!! Happy!! And I'm 14 man. Thanks for calling me stupid you jerk!!

  • Mac

    I highly doubt its live, since IphoneHacks would have announced its release

  • Lavender

    Previous articles clearly state that UltraSn0w will unlock (on a jailbroken iphone) any iphone OS from iphoneOS3.0 to iOS4.0 …
    … so … clarification please

  • Lavender

    So, is it that different iphone versions running the same OS have different baseband? I thought the baseband versions came with the OS versions …

  • paintmixer


  • paintmixer

    The iPhone 4 has 01.59.00 on it. The iOS 4 installs 05.13.04 onto the 3gs, but NOT the iPhone 4.

  • Cozze02

    Is this real or a really good video editor???

  • techny

    i hope there's a spirit unlock too….hehheheh

  • Robd

    Hi to everyone,
    My iphone is 3gs , 3.1.3 (7E18), firmware modem 05.12.01 , Bootloader 06.04 , model MC132T . I jailbraked with spirit and I could install Cydia. Everything works except phone calls. I also can use 3G connection with my TIM sim card with no problem. Is there something I can do to fix the modem for the phone calls ? I also used Ultrasn0w 0.93 but didn't fix the problem. Any idea ? Thanks

  • Sergio

    anyone have an ETA for the Spirit jb for 4.0?

  • saeed
