The Dev Team just released an updated version of their famous Mac jailbreak, PwnageTool 4.2. This new version of PwnageTool allows you to update your iPhone to a newer firmware while preserving your baseband. PwnageTool is the only jailbreak tool to let you do that, even though there are manual ways to update while preserving the baseband using TinyUmbrella.

In short, PwnageTool is unlockers’ favorite jailbreak as it allows to keep the unlock alive while still updating the iOS.

The Dev Team was able to make a few improvements to PwnageTool, notably a fix for the iBooks problem we reported this morning…

PwnageTool also includes two very recent improvements to the 4.2.1 JB:  iBooks was just fixed by @comex and @pushfix last night so that it works as intended on DRMed books, and the wifi problem on AppleTV 2G was fixed by @nitotv, @DHowett, and @saurik.  Both of these fixes will also be available in upcoming Cydia package updates, so if you’re already jailbroken you can wait for those updates rather than restore and jailbreak again.

The various components to the 4.2.1 untether (including a second exploit involving Mach-o headers) were worked out by 0naj, posixninja, and pod2g, and a nice writeup by 0naj is available on the wiki. The actual injection method uses geohot’s limerain exploit for most devices.  And even though 4.3 is just around the corner, the exploit used has already been closed in the latest 4.3 betas, so it made sense for the 4.2.1 untether to be released when it was.  It also appears that a security researcher named @i0n1c has a 4.3 untether ready for when Apple releases the final 4.3 FW, so it may not be a long wait at all with 4.3!

PwnageTool 4.2 will work with the iPhone 3G, 3GS, 4, Verizon, the iPad, iTouch 3G and 4G, and the Apple TV.

We have a tutorial on how to use PwnageTool to jailbreak your iPhone 4.2.1. You can download PwnageTool 4.2 from our downloads section.

    Used tiny umbrella and greenpois0n rc5 on ip4 the day they were released. Ran redsnow as well like others had to because of missing Cydia. Everything’ s been great except for an issue I noticed with large app store downloads (such as tomtom usa app) that fail everytime over both wifi and at&t 3g. Anyone else having this issue. I’m considering startingnover with Pwnagetool 4.2.

    @ seb. I’m not a noob but there are things I am not sure of. I read alot about all the jailbreaking and so on and at the present I am on a ip4
    Jailbroken with greenpoison on 4.1

    I have saved my sshh thing and I am happy with my phone at this time . But now all these new jailbreaks have showed up I’m debating wether to update. I want to b able to unlock when I am able.

    If I jailbreak with Pwnagetool 4.2, will I be able to do tethered Internet on my laptop? Also, how easy is it. I recently upgraded from my 3G to a 4, and used blackra1n on my old phone. Thanks

    • It seems that you’d be better off with GreenPois0n, if all you want to do is jailbreak.

      Once jailbroken, you can use MyWi to share your internet connection with your laptop.

        Hi Sebastian,

        Before this, anybody who upgrade their baseband to 06.15.00 cannot update their firmware to 4.2.1 or later due to baseband check.

        For sure, with this custom firmware i can update/restore to ios 4.2.1 without any problem.

        But, referring to your sentences “even though there are manual ways to update while preserving the baseband using TinyUmbrella”. Can this method (official iOS) applied to whom that upgrade their baseband to 06.15.00?

        Fyi, i has iphone 3gs (new bootrom).

        Thanks in advance.

      • Duff

        Thank you for the info. Is mywi as easy as snow? ( I think that was what was used with blackra1n)

  • Kristiana

    Question? I just bought the Iphone 4 (4.2.1 software) and I have tmobile and the lady told me I would be able to use it by unlock/jailbreaking it comes to find out I can’t until an unlocking code is released! Sooo does this mean that I can finally use my Iphone with my tmobile sim card??? Please help

    • EgoHot

      Nope. Unlock and Jailbreak are 2 different things. What you need is an unlock. No word on when an unlock will be out. My guess is either 4.3 or 5.0
