New iPhone 3GS 3.1.2 OOB Not Jailbreak Proof

Advertisements

A few days ago we have spoken that Apple Blocked Jailbreak in iPhone 3GS 3.1.2 OOB, due to a new version of ‘iBoot introduced by Apple to fix a security vulnerability that prevents the exploit 24kpwn. Today, Eric McDonald, a member of the DevTeam, said in a telephone interview to the Wired that there is no much to fear because even on these “new iPhone 3GS” will be able to run the Jailbreak. Well, this is a good news for those who just purchased a new unit of iPhone 3GS or all those users who wish to purchase the device in the coming days / months.

24kpwn was the longest standing hole in Apple pocket and finally Apple blocked it with a new iBoot Cat and mouse gameupdate. This was the first time when Apple introduced a new bootrom after the release of product, . Apple updated the iBoot –359.3 to iBoot –359.3.2 and the latest iBoot isn’t vulnerable to the 24kpwn exploit. McDonald explained that current tools will still work with the latest batch of iPhone 3GS units. The “24kpwn” exploit used to help jailbreak previous iPhones and iPod Touch devices only made it easier to boot up the hacked devices. The cat and mouse game isn’t finished yet, we can hope Dev team will find an alternative to 24kpwn exploit very soon. In short it’s still possible to jailbreak the newly shipped iPhone 3GS but in a tethered way. It’s all on Dev-Team to find a new exploit to enable untethered booting once again.  Many nerds around here are confused with a tethered and untethered jailbreak.

  • Tethered Jailbreak : If you shut down a jailbroken iPhone 3GS, or if it runs out of power, you can only turn it back on by plugging it into a computer.
  • Untethered Jailbreak : If you shut down a jailbroken iPhone 3GS, or if it runs out of power you can switch it on back with power button.

Summary : Apple didn’t blocked the jailbreak they just blocked a bit of code (24kpwn) that allowed for untethered jailbreaks in the first place.

    So.. Guys I think the best bet you have for an untethered jailbreak is to do a warranty exchange with a 3.1.2 replacement handset and chances are you will get it with the older bootrom, though the serial number will be from 2010 mine is …5k005595… and i was still able gto use blackrain to get an untethered jailbreak and unlock.

    I am unable to install Cydia on my iPhone 3gS 3.1.2/ 05.11.07 that I jailbroke/ unlocked using blackra1n and sn0w.

    Does ayone have a resolution for it?

    Hey there,

    I have an iPhone 3gS 3.1.2 05.11.07 – My iPhone is just like all of yours.. Productionweek after 40 (mine is productionweek 43) wich means it doesn’t get jailbroken properly.
    My internetconnection AND my Network drops every 30seconds for about 15seconds.
    Wich means text messages and phones don’t come or can be 3 hours late.
    Any idea what I can do about it? I also have the problem when i reboot my phone, I have too jailbreak it again. But that’s the least of my concerns. I am more occupied with getting a stable connection on my phone.
    Anyone can help me with that? x

    I have both an old 3GS (prior to 3.1.2) and a new (with 3.1.2). I upgrade the old one to 3.1.2 then JB and no problem at all. But the new one has the problem that everybody described, must jailbreak each time you power off/on. Don’t know if it’s important but both have modem firmware 05.11.07.

    Hello there, I just succesfully unlocked and jailbrake mi iphone 3GS but I forget to update from 3.1 to 3.1.2, my current baseband (firmware of the modem) is 05.11.07. Can I still do a clean update from Itunes and the re-run blacr1n again? Do I have to make a backup into Cydia? I neet to istall a program available only for 3.1.2

    Hey tony,
    It will boot up if you hook it back up to your computer and run blackra1n again. In fact, you have to run blackra1n every time to boot it after the jailbreak on a 3gs with 3.1.2. The development team is working to find a solution for an “untethered” jailbreak. Right now, it is tethered only, meaning to boot, you must have it hooked up to your computer with the usb cable and you must run blackra1n and it will boot your phone for you. If you don’t want it this way, you can restore your phone through itunes and wait until an untethered jailbreak is created. There is no other option at this time. Good luck to ya!

    by the way, is there any way to get the JB stabilised? like via any other method besides blackra1n which is an untethered JB for MC models?

  18. charles November 8, 2009 Reply

    i currently am using an iphone 3gs which i bought i few days back from hong kong. so it is factory unlocked. i tried to JB it but i had to do it twice to get back to my main screen. once i switched it off, the JB is gone and iphone back in DFU mode. seems to me that iphone models with MB are fine but like mine which is an MC, is facing the tethering problem…

    hey bro Kidaa?

    Apple is living in a jeopardy whether to or NOT to allow jailbreaking.
    On one side, By allowing it, they are losing big sum of revenue that they make through App Store program and on the other, if they don’t, they lose most innovative and customizable features.

    But, like any other business, Revenue is most important. So, they try to make jailbreaking bit more tedious and NOT intending to make it impossible.

    cheers Apple!

    They would never be like Microsoft — driving privacy on their own!

      @taranfx HAHA you are right either Apple should make the iPhone OS as open source or let the jailbreaker find their way. I don’t know why they want exclusivity on App store. Android will surely grab the iPhone market share very soon all we need is phone like HTC HD(Windows ATM)
