The Dev Team confirmed earlier today in a blog post that they will not be releasing a jailbreak for iOS 4.0.2. The last jailbreak released was JailbreakMe, which allowed a quick and easy jailbreak directly from the Safari browser, taking advantage of a security hole in the way PDF documents were handled. The patch has now been fixed by Apple with the recent release of iOS 4.0.2.

FW 4.0.2/3.2.2 was *only* released to fix the jailbreakme hole. With FW 4.1 still in its beta stages, it makes no sense to escalate the “cat & mouse” with Apple for FW updates that only fix the jailbreak holes. To quote WOPR, “the only winning move is not to play”.

If the cat & mouse game escalates too quickly, especially during beta FW periods, nobody but Apple benefits. For this reason, there won’t be a 4.0.2/3.2.2 jailbreak specifically during the period where 4.0.2/3.2.2 is the latest public release. At best, some future 4.1x FW jailbreak *may* be compatible with 4.0.2/3.2.2 (but don’t count on that).

So if you were holding your breath for a 4.0.2 jailbreak, you’re going to have to keep waiting. In the meantime, if you accidentally updated to 4.0.2 and want to go back to 4.0.1 or iOS 4, you can follow these instructions to downgrade your iPhone.

For the most up-to-date jailbreak information, make sure to refer to our jailbreak section on the site.

    hey Seb, co-worker of mine wants to buy an iPhone & will of course get a 4.0.2 model unfortunately. could that be downgraded, or would it have to have been 4.0.1 first? maybe a dumb question…

    • No, it couldn’t be downgraded. You would have had to be on 4.0.1 at some point AND save your SHSH blobs either locally or even better, on Saurik’s server to allow downgrading.

    • Burge

      He might be lucky and get one on 4.0.1

  • TattoozNTech

    LOVE the new site btw… very kool!

  • Smart.

  • jb

    Would the following be possible:
    If you had a friend who had 4.0.1 and saved the SHSH blobs to his computer. Could you use his to downgrade your iPhone?
    Just wondering…

    • Burge

      No shsh are for your iPhone only.

  • TattoozNTech

    what’s the likelihood of gettin a new iPhone on 4.0.1? anyone have any idea?

    • Turbo

      That was my ? I sold my jailbroken 3g with shsh files saved on sauriks server. Buying a ip4 was hoping to still use jailbreakme is it possible?

      • For everyone who wants to know the possibility of he/she getting an iphone 4 with firmware 4.0.1 or 4.0.2:

        Simply put, it’s a gamble. If you buy an iphone 4 that was manufactured before the update you’ll get iOS 4.0.1; if not, then you know the bad luck you’ll receive on your end. Once Apple boxes an iphone that’s it. They don’t reopen the ones in stock to perform a firmware upgrade then repackage it. (If they did, well at least we know why we pay so much for the device) On the serious side, it’s still a gamble.

    Thanks Burge.
    Oh well…I still have my JB’d 3GS

  • lee

    dang is that mean i’m holding a piece of junk on my hand? wat was i thinkin….dammmmm

  • Solidus

    It’s funny how all of a sudden Apple supposedly ran out of iphone 4’s to sell when this new FW is released……I think it was intentional. I guess I won’t be buying an iPhone 4 just yet, cause I need my customization lol

  • Apple everything

    Be nice if the devs could find away round the downgrade system these guys are good maybe 1 day

  • Z

    Has anyone tried restoring the phone to 4.0.1 by using the shift when clicking restore? My friend managed to do it, so I presume that FW 4.0.1 is still being authorized. Give it a try.

    • Burge

      Apple stop signing a few days ago

  • Eeeehhhh, I don’t quite follow here….

    So far I have jailbroken 3 iPhones on 4.0.2, so what is this about?
    Used the guides on RedmondPie, and I’m quite sure there was a guide around here somwhere too – anyways..- we did it to 3 iPhones, so I feel like I’m missing something here…

    • Burge

      And they were 3G yes !
      3GS and i4 carnt be done on 4.0.2

      • Burge

        Update— old bootrom 3GS yes
        Mc model no

    • You can still jailbreak a 3G iOS 4.0.2 with RedSn0w, but you can’t jb a 3GS or iPhone 4.

  • jeme2003

    i don’t understand why people upgread iso 4.0 to iso 4.0.1 or 4.0.2 ?

  • SCT1969

    Um….. I know I am fairly new at this jailbreaking thing, but, I have iPhone 3G, just upgraded to 4.0.2, and jailbroke with redsn0w 9.5b5-5 using a 4.0 ipsw file. It has only been a week now but everything seems to be working fine. Installed cydia apps and modded my phone. 1 hickup, do NOT enable multitasking, uses tooooo much memory.

  • Sue JobSon

    Balls…. Exact same thing happened to me last year upgraded just after Apple released the major software update and no JB for ages!! Why can’t someone figure out how to downgrade without the shsh …. Aaarrrgh!! it seems so simple!!
    Anyway, please make me smile and tell us exactly when 4.1 is likely to be out?

  • Fidan

  • lee

    OK all these heroic who said they did it and not sharing the true or prove it by video or at least upload the FW package… yall either lying or do not belong to this blog at all. While yall run into here and asked for help… we came out with a solution and asked for your little contribution back and yall ignored it. Well congratz on ur successful unlocked phone and GTFO if you not willing to help the rest get it. Stop posting reply that you did it and not willing to help or show how to…

  • Fidan
  • @LEE if you got a 4.0.2 , then go to the store with a “problem” on the phone… the replacement device they will give you is 4.0.1

  • lee

    lol unfortunately that replacement phone is not a brand new phone its refurbished phone that returned to apple and they refurbished it and give to customer as replacement.
