iOS 4.1 Jailbreak Ready for Release

SPONSORED LINKS

Many of our readers informed about a possible announcement of jailbreak for iOS 4.1 firmware that is about to be released on 8th Sept [developers version already out] has already been jailbroken by iPhone Dev Team. A recent tweet from Muscle Nerd suggest that Comex will try to pull a trifecta by releasing a Userland Jailbreak similar to JailbreakMe.com to jailbreak iOS 4.1 for all idevices. If he fails in doing so , then a bootrom exploits will be released instead .

iOS 4.1 jailbreak

What is Userland Jailbreak ?

Userland Jailbreak works on the iOS firmware and exploits a loophole to jailbreak your device . This is also called untethered jailbreak . Spirit and JailbreakMe were Userland Jailbreak tools . Userland jailbreak can be fixed very easily using patch on every new iOS firmware Apple will release.

Modmyi Says :

Userland Jailbreak can be considered as a special app which runs at every startup, after the boot process, but before the springboard has loaded, and which each time modifies the firmware in the memory, allowing you to get root privileges.

About BootRom Exploit ?

I wont explain about this much in this post , just in brief that , iBoot exploit gives hardware level access to the device which cannot be fixed as easily by Apple just by releasing a iOS software patch. They’ll have to fix it just at the manufacturing level , so this will only be possible as they roll out new devices. One example of iBoot Jailbreak is Pwnage Tool .

What do we suggest :

Wait for Sept 8 release of iOS 4.1 Firmware . Let us confirm about the Jailbreak release , and verify its working before you can attempt it on your device. To get the latest alerts , please subscribe to our JailbreakMe alerts and Join our Facebook Fanpage for updated news 24×7.

  12. Iphone Blogger says:

    Its coming dude . keep patience …

    Dev Team Says :

    Please stay away from this 4.1 release until a safe jailbreak procedure (which also preserves ultrasn0w) is developed and released.

  13. Shaome says:

    Damn, I´ve been waitin for a long time now…!!! Sooooon we will all be happy!!!
    A big thanks for the people at the Dev Team!!

  14. jay says:

    so dont download 4.1 ??

    • Iphone Blogger says:

      save SHSH blobs . then attemp upgrade , so u can revert .

      • khEn says:

        So here’s my question? Is it possible to save shsh on iphone 4 even its not jailbroken? Is anyone save their shsh blobs? Then upgrade it to 4.1 then downgrade it again to 4.0.2!? Asap

      • BBlood says:

        “Is it possible to save shsh on iphone 4 even its not jailbroken?”
        Yes, it’s possible.
        1) Install JAMA Machine
        2) run Umbrella
        That’s it!
        I did it today and it was my first time.

      • khEn says:

        Ohhhhh!!! That’s awesome men!!!! Thnx a lot bblood!!!!

  15. Mitch says:

    Well just update to 4.2 on my 3g. Just waiting for the jailbreak and I will be set. Never done a jailbreak so this is going to be new for me.

  16. Stripeyone says:

    I have 4.0.2 as factory on my iPhone 4 there is no jailbreak for this firmware so would there be any real issue with upgrading to iOS 4.1 if I still want to jailbreak or do I sit tight and wait?

  17. Raykkazza says:

    I need it :/

  18. Stripeyone says:

    A friend of mine just tried to do the official iOS 4.1 update via iTunes and could not complete as file was corrupt

    • Hikmat says:

      Any1 else tried and could confirm that ?? so the rest of us with 4.0.2 wouldn’t attempt to update now

      • T says:

        i read in another article that if u have 4.0.2 that u should just go and update because 4.0.2 wasnt an offical update it was just a patch to fix the jailbreaks so there wont be a jailbreak for 4.0.2 since it wasnt an official update so u should upgrade to 4.1 because that is what the new jailbreak will be for

  19. Leandro says:

    Well I would recommend you update to 4,1 but using tinyUmbrela so you keep the Modem Baseband Untouched, in case you get an 4,1 jailbreak the possibility of the 1,59 unlock work on 4.1 might be higher

  20. bobotheclown says:

    so i have an iphone 4 with 4.0.2 is there anyway for me to jailbreak ?

  21. Raykkazza says:

    keep away of 4.1 for now :P is the better , the new jail is very soon, i wish XD.

    • Stripeyone says:

      I have no jailbreak as I have iOS 4.0.2 so for me I don’t think there will be a problem with going to iOS 4.1if there is no jailbreak yet and just wait for it or is there going go be a procedure that requires you to install software before updating to iOS 4.1

  22. Filipe says:

    Hey guys.
    So I just got an iPhone 4 with fw 4.0.2 out of the box. I read that fw 4.1 might be able to jailbreak but not for sure yet since it’s not out right? What should I do now? Wait for a jailbreak to come out for 4.0.2 or 4.1? Should I upgrade to 4.1 straight away either way?

    • Hikmat says:

      Well there isnt going to be a jail break for 4.0.2 so i think all of us ppl with factory installed 4.0.2 should just upgrade to 4.1 since JB will come for that version.

  23. Januar says:

    Just found that upgrade to iOS 4.1 has just been available through iTunes. Seems it is the official one (not for developer).

  24. tonkpils says:

    i bought one last weekend in the US, apple store. saved a lot compared to Euro prices. over 200 euro savings!!!. And now i really do not mind waiting for jailbreak. the 4.1 soft is very nice. HRD pictures are awesome quality…. Surely new jailbreak won’t be late. there has been so many beta before the final official one.

  25. selenite says:

    I’d say don’t upgrade to 4.1 until you know for sure that there is a jailbreak for 4.1 because as it is right now, version 4.1 will change your baseband so that the phone can NOT be unlocked.

    As quoted from the Dev Team,”There’s currently no known way to revert your baseband — if you update your baseband you’ll lose the ultrasn0w unlock, possible forever.”

    Yes, and even if you have 4.0.2, do not upgrade!

    • Siddharth says:

      U can upgrade to 4.1 without upgrading ur baseband. Chk out this link i was able to successfully upgrade to 4.1 without upgarding my baseband version. Its still at 1.59

      http://www.iphone4jailbreak.org/upgrade-to-ios-4-1-without-risking-unlocked-baseband.html

    • tonkpils says:

      jesus… i am totally lost… what i understood is that the iphone i got from the US had the 4.0.2 already in. the baseband was already different than the others before. Now it is upgraded to 4.1. Apparently you are telling me that i will not able to jailbreak it because the baseband is different. Coming from software development, this sounds illogical. The DevTeam is now working on solutions for telephone that are not the latest on the market?

  26. Ruben says:

    Just bough my iPhone 4 this morning from the Apple Store and it seems it already comes with the 4.1 FW installed (Apple doesn’t lose time). When can we expect to see a jailbreak and baseband unlock for it . . . I’m traveling overseas and need it BAD. Otherwise my roaming charges will be up the wazoo!

  27. T says:

    they need to hurry the hell up and release the jail break already shit lol cant even use my iphone 4 to its full potential yet got dammit

  28. khEn says:

    Ohhhhh?!!!! I been checking this site very hour every minute! Hahaha can’t really wait!!!

  29. Raykkazza says:

    x.x i cant wait more …

  30. Zing says:

  31. Raykkazza says:

    yes http://twitter.com/musclenerd ….

    confirmed works !!!
    :P finaly very very soon we will have the jb.

  32. NEWBY says:

    Is there a website describing on how to jailbreak. What it does, and what you can do with the phone once you jailbreak it?

    • Hikmat says:

      This site does that, just search in the forum and u’ll find all u need bout jb and unlocking

    • Iphone Blogger says:

      ahh , i just added the FAQ section for the basic question. Though just added only a few basic questions there , i will update it as i manage some time.

      For you , see top navigation bar , you will see FAQ … at extreme right .

      Thanks

  33. Andy says:

    I got my I4 after 4.0.2 released the 2nd day. Been waiting for so so long.. finally i can hear something that makes my day. been carry I4 with me just using it like an Ipod.. :( … THIS MAKES MY DAY!!!

  34. Stripeyone says:

    Bootrom exploit confirmed to work and to be realeased soon

  35. spiros says:

    hi i buy iphone 4 today with os 4.1 os when jb rdy for os 4.1??

  36. Andrew says:

    looks like Apple has got the better of the dev team this time no jailbreak for over a month now. this is costing developers a lot of money.

    if they cannot get the jailbreak to work reliably then it will be hard to convince the users and developers that it is a viable solution or platform to develop apps for.

    Apple does not care that you had a legal victory on jail-breaking if that victory does not prevent them from patching the jailbreak exploits!!!!!!!!!

    Think on this …………..

    • Iphone Blogger says:

      Thanks for leaving your views Andrew. Yet its right , not having a JB for a long time is costing Dev’s a lot of money .

    • Wophat says:

      Seem like these kids have taken Apple to the s*** house a few times LOL keep up the good work

  37. T says:

    is the a difference between jailbreaking and unlocking a iphone?
    can somebody explain what baseband is and how it affects the jailbreak proccess if i update the phone? or at least provide a helpful link?

  38. Zing says:

    from 9 sep you’ll likely start seeing iTunes innocently offer you a new version of iOS…version 4.1. Don’t accept it…it’s a trap!

  39. Copieg says:

    I tried to put my iPhone4 in to DFU mode and itunes shut it down and made me restore it!! i now have 4.1!!!!!!!!!!!!!!!!!!!!!! NOT HAPPY!!

    I’m new to all the jailbreak stuff so tghis was going to be my first time. All i was trying to do was save my shsh things. This site is not very
    clear for people doing this for the first time (and not tech savy!) can you please make a simple step by step on how to jail break your phone for the first time. with links to what you need to download to get your free apps etc. I’m pretty pi**ed off that i now have the new update as it looks like i may not be able to jail break my phone!

    • Iphone Blogger says:

      Just calm down . We’ll get a solution for you soon

      • Copieg says:

        sorry, but everyone i have spoken to said this was really easy to do. and from i have seen it isn’t!

        When the 4.1 jail break comes out, do i just download it from my iphone and that it? nothing else??

    • Wophat says:

      Are you insane. The last jail break the was out couldnt have been an easier just go to a web page and click the link it was that simple. Lay of the blunts for a few minutes next time

  40. Harshneet says:

        most of us ppl with the 4.0.2 r dyin to have the jail break cuz so far i’ve the most expensive ipod, ive uploaded contacts and everythig but i still need to unlock badly !! but in the same time we dnt want a jb that would crash the OS cuz of poor testing, id rather wait a few more days to get a better workin jb, as long as its soon as well :P i dnt wanna spend months with a $760 ipod :P

        Give them time, i expect it to be up this week

  45. Zing says:

    But can someone tell me should I upgrade my out of the box iPhone4 4.0.2 to 4.1 by itune now???
    Cause I read a msg about muscle nerd advise we should take this upgrade until 4.1 jb release….

  48. AB says:

    Hi, I upgrade to 4.1 (stupid i know) and managed to downgrade to 4.0 with cydia shsh blobs saved. But the baseband is now at 05.14.xx and not unlockable with ultrasn0w or any other unlocking tool… for now. Will the jailbreak for 4.1 include or come with a revised ultrasn0w release which will work on the upgraded baseband? Or do i need to wait for a new fuzzyband to downgrade the firmware…?

    Thanks!!

  49. Zing says:

    don ugrade !!

  53. Lucygoosy says:

    • HK Iphone sad user says:

      Bro,
      I’m same to you and my new iphone4 like a rubbish in home…
      Just can take the 3GS for daily use until the new jb come out.
      Anyway, look forward the dev team heros announce the newest super jb.

  55. Zing says:

  56. Bob says:

  57. Korhan says:

    :(

    waiting
    waiting
    waiting

    iphone4 with ios4.1

    :(

  58. BlackRain says:

    maybe there is no jailbreak for iOS 4.1.
    maybe apple has done his homeworke.
    maybe all iPhones which comes out with 4.0.2 will be locked for ever.

    i think there won´t be a jailbreak for iOS 4.1

  59. IPONEE says:

    Hey i have a iphone 3GS with 4.0.2 and want to Jailbreak it can you guys tell me if there is an jail break and how would i do that?
    thanks

  60. Rey says:

    Will it be compatible with itunes 10? Will it unlock as well?

  61. Marco333 says:

    I have a iphone 4 with 4.0.2 like everyone else I want to know when the jailbreak is gonna be ready. Does anyone know?!?!?

    • Iphone Blogger says:

      JB is not coming before the end of this month . Also a iOS 4.2 is going to be relased in november , so chances are even thin …. Dev team doesnt want to get patches again for thr whol months work…

      • Hikmat says:

        Does that mean they might nt release a jb for 4.1 as well ? :S explain plz cuz we all read that green poison should be it and should be released soon

      • Iphone Blogger says:

        it all depends on apple’s mood . Pray that they release iOS 4.2 soon , as this would be their final release this year ie 4.2 that will be released along iPAd . or probably its a Simple trick by Mr Jobs, and there is nothing much in iOS 4.2 . Just to keep the iphone dev team from releasing any jailbreak …. it has all become a cat and mouse game. Apple has the technology , and iphone dev are low on resources and man power , no doubt its taking them so much time after the first iphone 4 jailbreak [jailbreakme]

      • Iphone Blogger says:

        Apple has fixed the firmware from being jailbroken at hardware level . si its hard to jb this one , as you see iphone 3GS and older 3G can easily be jailbroken …. its in the iphone 4 hardware , thats causing the delay in jailbreaking its firmware … Apple spends so much time not only developing the phone but also making it jailbreak proof … such a waste to time and money . if Apple saved that money on reasearch and development and made the phone a little cheaper for the people of developing countries to afford , it would have been an generous effort from Apple’s part . They just dont want the phone for everyone , just the exclusive category of elite users .. damn u Apple .. :X

  62. Rickardo says:

    I have read on various pages that the redsnow 9.5 beta 5, is now capable of unlocking the, MB models, as always!!! I am still VERY weary of updating, SO PLEASE let me know if its SAFE!!!

    IS IT SAFE YET????????????
    (i have an ipod touch 2g, so im not botherd about baseband shi** lol)

    • Rickardo says:

      Edit – I got tired of waiting, lol, so i went ahead and did it! I have used redsn0w Beta 5, and with my firmware as ios4.1, i jailbroke using the 4.0 firmware, and atm i have had several problems, so i have restored it back to 4.1 w/o cydia. Next step is to try it with 4.1

      • Rickardo says:

        Edit – Sorry one more major problem, i cant turn the bloody thing off to restore it!!! AHHHHH
        DO NOT TRY THIS AT HOME ladies and gents!!!

  63. Zin says:

    hold ur Horses its jus matter of days for d jb to b out .. as u can c jb for 4.1 for 3g n 3gs is out so jus chilll !!! n wait

    • Amz says:

      Were do I get the jail break for this then?

      iPhone 3GS firmware 4.1…ne1??

    • Rickardo says:

      Yer but surely they could have done it by now,
      JUS TO SAY!
      that i honour the Dev Team for their hard work and effort, but when it comes down to deadlines, theyve got everyone on the edge of their seats checking every 5mins!!!

      DONT THEY KNOW…
      that all the poor people in the world have windows operating systems not MAC???

  64. Icrazy says:

    I think it’s all bullish*t…. I don’t think their is gonna be a JB for the iPhone 4 4.0.2…… all you hear is 4.1… Now 4.2…… @ the end of this month…. Well ain’t we @ the end of this month…… I think apple has put a true fix on this one! Sorry but true…… And that Green poison is all bullish*t too!

    • Hikmat says:

      Well then wen its released simply dnt use it and continue using your limited access “ipod” !

      • Rickardo says:

        Well said… I updated my ipod 2g to 4.1 and im just dying to get it jailbroken!!! Now ive been left with a useless brick until the windows version is released!!!!

        GOD BLESS THE DEV TEAM!!!!!!
        (i just wish theyd hurry up already)

        Windows version plz????

  65. Antibiotik says:

    Its true, this time its hard to break this shi*, unfortunatly its gonna be a long wait, but im sure that hackers will do it, we belive in you hackers! Go for it! And victory awaits for u!

  66. Daniel says:
