Apple Releases iOS 4.3.4 with Fix for JailbreakMe Exploit

By , Jul 15, 2011

Apple has released iOS 4.3.4 for the iPhone, iPod touch and iPad. This update is now available in iTunes and has been released to fix the PDF exploit uncovered and distributed by Comex in the latest addition of JailbreakMe.

iOS 4.3.4 can be applied to your iDevice by updating your software in iTunes.

We obviously warn you to not update to 4.3.4 if you are on a jailbroken device. JailbreakMe users will need to stay on 4.3.3 to maintain their untethered jailbreak.

We’ll let you know anything else we hear about 4.3.4, but for right now, stay away if you’re jailbroken. Now would also be a very good time to backup your SHSH blobs in the event that you need to downgrade.

iOS 4.2.9 for the Verizon iPhone has also been released.

This is how Apple describes the update:

“Impact: Viewing a maliciously crafted PDF file may lead to an unexpected application termination or arbitrary code execution

Description: A buffer overflow exists in FreeType’s handling of TrueType fonts. Viewing a maliciously crafted PDF file may lead to an unexpected application termination or arbitrary code execution.”

For direct links to iOS 4.3.4/4.2.9, head over to our downloads section.

UPDATE: The Dev Team has released a tethered RedSn0w jailbreak for iOS 4.3.4. For more information, go here.

    Does iconic untether with redsnow still work

      No one’s 100% sure at the moment, but for now stay away.

    Hate this cat and mouse game Apple is doin. Cant they just leave us alone?

    • DomPerignon

      No; Apple (Steve Jobs) hates the jailbreak community. Remember that jailbreakers/hackers invaded their “patented firmware” and they also are not profiting from any apps for jailbroken phones.

      • Acolz

        People don’t only jailbreak to download patched ipa apps dude lol

    • shinratdr

      What are they supposed to do? Leave a publicly known vulnerability unpatched? It’s not about “leaving you alone”, it’s about maintaining the sandbox. Any time a jailbreak is released (especially one this bad), that means a serious hole was found and leaving it unpatched after being notified about it is dangerous to all iPhone users, not to mention irresponsible.

    It’s funny because my name is Alex.

  • Alex L

    they are trying to attract as much people as they can. they want people to buy the idevices.

  • Michael

    How long until some1 posts here saying they updated by mistake and is there a jailbreak lol

    • soccerkrzy

      If that happened to me, I would just go to iOS5

    • DomPerignon

      It will not take long. Morons always show up early.

      • Mac

        hi I just updated by mistake is there
        any way to jailbreak now 

      • DomPerignon

        Ah; I almost forgot! The next moronic question that only MORONS ask 100 times is: When is the jailbreak for 4.3.4 coming out? knowing that iOS 4.3.4 doesn’t add anything new.

  • soccerkrzy

    Probably safe to assume Snowbreeze still works, but will wait for a confirmation. Sounds like Apple just pushed this to cover the pdf exploit because they’re sick of hearing how jailbreakers fix their security faster.

  • Varun

    Oh man, this is very bad for me timing wise. I am just about to get a new ipad in the next few days. And it would most probably be on a lower firmware than 4.3.3. If it is so, can I still install 4.3.3 and jailbreak it or will Apple stop me from installing 4.3.3?

    • James

      I bought my pad 2 weeks ago and it had 4.33 so there is hope for you!

    • http://twitter.com/jgns jgns

      If you bought an iPad today, it would have 4.3.3. Even if you were lucky enough to get one with 4.3.3, Apple cannot stop you from going to 4.3.3 or make you go to 4.3.4. And if they deleted 4.3.3 from their download sites, many people out there (me) would be able to provide you with the ipsw.

      • http://twitter.com/jgns jgns

        Oops, correction even if you were lucky enough to get one with 4.3.2*

    • Juan

      In the event that your new iPad2 is on firmware 4.3.4 out of the box, you are completely out of luck. end of story.. You can’t install 4.3.3 unless you have the SHSH blob for that particular device, which you won’t have since Apple will stop signing for 4.3.3 soon.

      In the event your new iPad2 is on firmware 4.3.3, then head on over to jailbreakme.com and jailbreak away. in addition, you may or may not be able to get your SHSH signed so in the event you iPad goes tits up, you will be forced to 4.3.4 (or whatever happens to be the current firmware).

      • Anon

        You actually CAN jailbreak back to 4.3.3 without a saved SHSH blob.
        Get your facts right before posting, fuckwad.

    • shinratdr

      According to tweets retweeted by comex, Apple is still signing 4.3.3 releases. So in other words, yes, but nobody knows for how much longer.

  • PizzaFace

    You jailbreakers are all pimply faced losers…… Just leave Apple alone!

    Has anybody seen my acne cream?

    • UtahUte88

      And this coming from someones name that is “PizzaFace”….

      If you aren’t for jailbreaking why the hell do you even look at this website?

      • CleanShaven

        He is making a joke….. That is pretty obvious. And his Go Coug’s was a pretty good comeback me thinks.

  • PizzaFace

    Oh yah….. Well go Cougs!

  • Josh

    Wait.. Maybe I’m not getting it right. APPLE is releasing an official firmware to fix something that involves JAILBREAKING?

    (As I said, maybe I’m not getting it right. Do correct me)

    • Ken

      No, Apple is releasing an update to fix a hole in their software that was discovered and used by the Jailbreak community to gain access to their iDevices and use Jailbreakme.com to jailbreak their iDevice. This same hole could be used by hackers to gain unauthorized access to your iDevice.

    • soccerkrzy

      You’re right about one part, and that’s that you’re wrong. Moron.

  • Cameron MacGregor

    Is 4.3.4 able to be jailbroken unteathered via RedSnow?

    • http://gmail Tbv

      We would have to wait to see if Redsn0w needs updating for an untethered JB on IOS 4.3.4, the same applies to Sn0wbreeze. And for the iPad 2, there will be no current jailbreak for 4.3.4, unless there is another PDF exploit found by Comex. Redsn0w & Sn0wbreeze is useless on the iPad 2 without a bootrom exploit.

  • n00bie dUDe

    I just bought a brand new iPad 2 not knowing that Apple released a patch already and came bundled with 4.3.4. I tried to return it because it couldn’t be jailbroken and they told me that I can not get a refund just because it can’t be jailbroken and then proceeded to laugh at me. I thought jailbreaking was legal? I don’t know how to use any other jailbreak tools and was looking forward to jailbreakme.com method. Can anyone help me?

    • iComedian

      redsnow or snowbreeze

    • kokhean

      Download the 4.3.3 IPSW file and restore to that. Apple is still signing 4.3.3.

  • fx3861

    Nope update tp 4.3.4 and try to jailbreak with redsnow but processes done it goes back to restore mode hence downgrade back to 4.3.3 seem it nulls the limerain process

  • sam

    Is Gevey unlock working for 4.3.4??

  • bada

    I have successfully Jailbroken iOS 4.3.4 with the latest redsn0w by pointing it toward iOS 4.3.3. I own iPhone 3GS (old bootrom).

  • Freddixx

    I am still on 4.2.1 iPhone 4 GSM Greenp0ison jailbreak. How can I safely upgrade to 4.3.3, prefererably with Comex’s JailbreakMe? I have my 4.3.3 blobs on Cydia and do not care about my baseband being updated as I have a carrier unlock. Please some advice.

    • Burge

      Download the ipsw for 4.3.3 and just do a restore to that…on a pc hold shift when you click restore , than selet you ipsw that you downloaded …at the mo apple is still signing 4.3.3 so no need to use tinyumbella

      • Freddixx

        Thank you, Burge.

    Is Apple still signing 4.3.3? I have a BNIB iPhone 4 on 4.2.1 (i Think) that I want to JB using jailbreakme…. Just want to know if I can Shift+ Restore to 4.3.3 that i have locally downloaded from felixburns.de???? Anyone done this today? I know last night Apple was still signing 4.3.3, but how about now?

    • Frankie

      @Kingkronikk: Well, last night I downloaded the ipsw from the downloads section in this blog, did a shift + restore in itunes and when the phone was ready to be used again i just went to jailbreakme.com and voila! Jailbroken and ready!

      So you might do that.

      For the morons asking if there is a jailbreak for 4.3.4, is it really necessary to upgrade everytime a new FW comes out?
      Stick to 4.3.3 since the new one doesnt add Anything new.
