pwnagetooliOS 4.0.1 for iPhone was released a few hours ago and those of you who have an iPhone 3G are already able to update and jailbreak iOS 4.0.1 using RedSn0w 0.9.5b5-5. Note that RedSn0w will jailbreak the iPhone 3G only. At this time, there is no jailbreak for other devices on iOS 4.0.1, which is why you should not update if you rely on your jailbreak.

Instructions to jailbreak your iPhone iOS 4.0.1 with RedSn0w remain the same except you must update to iOS 4.0.1 and point RedSn0w at the 4.0 IPSW even though you’re at 4.0.1.

The Dev Team and Comex are expected to release an update to Spirit sometimes soon. This new version of Spirit will most likely jailbreak all devices on 4.0.1.

Stay tuned for more info!

  • Updated my iPhone 3G to 4.0.1 and successfully jailbroke it with redsn0w_win_0.9.5b5-5.

    You must download the 4.0ipsw first and browse for it when redsn0w says so.

    For those who still get stuck contact me cos I know how frustrating it can be when you can’t get an answer!

  • takean

    I can’t get mine to jailbreak at all. I have tried numerous times now and to no avail. It sometimes locks up and sometimes will go all the way to the screen with “downloading Jailbreak data”…but the iphone always turns off after about 20 to 30 minutes…and no matter how much longer i leave it…even 2 hours, it doesn’t complete it for some reason. When ever I boot it up, no cydia, nothing. so not sure what i’m even doing wrong…lol.

    I have followed the previous instructions for the 4.0 jailbreak as well as these newer ones for the 4.0.1 and none of them work. I have tried the latest redsnow as well as a few earlier versions before that were supporting os4 and nada. If someone can help me out here I sure would love it.

    PS…i have a 3g 16gb

    takean –

    I was having trouble with my iPhone 3GS getting stuck during the “Restoring iPhone Software” phase. I followed the directions here (http://forums.macrumors.com/showthread.php?t=920629&highlight=) and it solved my problem.

    Not sure if this is the same issue you are having, but my phone was also locking up during the firmware install for 2hrs+ until I followed these instructions on my Mac.

  • Blasphemous

    What fixed my problem. I restored my 3G 8gb using iTunes 9.2 of course and then I followed the instructions on top. The whole process took about about 1hour and half. 1+ hour to restore and about 2-4 to jail break and unlock. Oh I did cancel background wallpaper setting. I did install multitasking. Good luck

  • takean

    what my phone is doing though is the downloading jailbreak data picture is going away and my phone appears to be shutting off…is it really? It isn’t rebooting like it should and I have to turn it on by the power button for 2 seconds. It just shuts off for some reason. I’ll do it again and just leave it all day long…but i’m pretty sure its just turning off

    • K

      I am having the same problem!!!
      Please somebody help.

  • Blasphemous

    Man that sucks I don’t know what to say to that taakean. Keep at it. I hope you can fix it

  • thanks fo the helpp 😀

  • im on 4.0.1 jailbreak and ulock toooo!

  • Freddo

    Ok, did the jailbreak and unlock successfully with iOS 4 (on an iphone 3g) after some initial heartburn. However, when i turn 3g on, it loses all signal and wont allow the phone to work. I know during the process it said to turn 3g off or it will cause catastrophic failure. So I did. However, do I now have to leave it off forever or am I doing something wrong? Looking for you smarter people to help me out. Oh, I used redsn0w and cyndia….help!

  • blasphemous

    freddo. same thing happen to me. i restored the iphone and followed the instructions on top of this page and that was it my phone is super nice now. i hope that helps good luck

  • Yves

    When running redsn0w_win_0.9.5b5-5 at the last ‘waiting for reboot’ it seems to freeze. Phone not booted, app stuck at that DFU screen. I tried on two computers now, same result. Any ideas as to what I’m doing wrong?

  • woodstock

    Apologies in advance if this is a stupid-ass question. I just received and activated my iPhone 4 and would like to sell my old 3G, which I upgraded to 4.0.1 (8gb). I cleared all the data and restored it to factory settings. I’d like to JB and unlock it now. Will I screw up my current iTunes settings and data that I need for the iPhone 4 by tethering the 3G? Should I do the entire process on another computer? Many thanks for any advice you might have. I’m hoping this will be a relatively painless process….

  • Marcus Castro

    Umm i have a 3g 16gb and jailbroke my iPhone using redsn0w and it seemed to work fine, I used installous to download apps, but whenever i do so they open but seem to close almost immediately. Even settings and app store bought apps seem to get a little crazy sometimes. I’ve looked everywhere and can’t find an answer…HELP PLEASE
