    IReb v 4.0 really fix the first problem (incorrect jailbreak by redsnow that cause all the mentioned problems)
    After using IReb you can restore old config from your iTunes. I think next time I’ll use green poison to jailbreak it.

    For all those who are seeing “waiting for reboot”, i got it resolved. I am not sure which one did the trick. I am describing it here –

    In Principle, it tells you to perform these three steps.
    1) Hold power button for 3 sec
    2) Without releasing power button, hold home button as well for 10 sec
    3) Release power button and keep holding home button.

    In some cases, after performing step 1 and step 2, religiously, the iphone does not boot up.

    Here is what Santhosh Garlapad (co-worker) did to get it to work –

    1) Hold the power button for 6-7 seconds (try little longer if you think so, but not too long)
    2) Without releasing the power button, Hold the Home button for 4-6 seconds
    3) Release the power button while continueing to hold the home button as long as you see the “HardDrive picture” (stating waiting to download jailbreak software etc…)

    I am not misleading anyone. I fought myself for two days doing the initial steps while my iphone was just dieing and never rebooted. My Coworker got this to work easily.

    At home while i was trying i had Windows XP Home Edition, but when i tried the new steps with my co-worker, i tried it on my office machine running Windows XP Business Edition (any guesses if that could be the problem, no i dont think so). But suggest other option to try it on other machines too.

  16. Greg.

    Ok I have an iPod touch 3G (3.1.3) that I upgraded to ios 4.0 the same day it came out is there a jailbreak available for my iPod? I’ve been searching and searching.

  17. Tyler.

    i did all of this but after the dfu mode the screen says waiting for reboot and it just sits there what do i do!!!!!!!

  18. Jek.

    I’m working on it. I’m not auctally making a software, but trying to use pwnagetool I haven’t been able to try it yet. I’ll comment after I try.

  19. Jek.

    I think It May work if u use pwnagetool with a mc model iPod touch 2g. I haven’t been able to try I yet, but I will soon. It should work.

  20. John.

    Using redsnow Browse I got: please select the corresponding
    ipsw for your current firmware unable to recognize specified IPSW.

    please help!

    I have a 3G iPod touch, Jailbroken on OS 3 with Spirit, then upgraded to iOS4. My iPod is now half-jailbroken. I lost Cydia, and backgrounds and stuff, but my name and numerical battery is still displayed. Will I still be able to re-jailbreak it? Need to know this now please, thanks.

  23. Harley.


    I am buying a newly jail broken (ios4) iphone 3g. I do not have an iphone plan but I do have AT&T. I should still be able to use basic phone services my plan covers right? It won’t be locked to the old SIM that used it?

  24. Luke.

    Jb my 2nd touch non mc today it worked fine but cydia apps kept crashing e.g ifile, ibluenova, icon support

  25. Joe Vegas.

    So just so I’m clear. I have a jailbroken unlocked iphone on 3.0 firmware with T-mobile. Am I able to upgrade to iOS4? If yes, can you direct me to the easiest site to do this?

  26. chaitu.

    Thanks to Redsn0w… it made my ipod touch 2G jailbreaked …… after breaking my head using Sn0wbreeze for 4 times to jail break it….

    You rocked…. 🙂

  27. cheap.

    I have a 3G that was originally on 3.1.3 and jailbroken with Spirit. It’s now on iOS 4. Should I downgrade or can I use redsn0w to just jailbreak (not looking to unlock). Thanks in advance guys, been looking all afternoon for a straight answer.

  28. elmo.

    guys, ios4 worked on my iphone 3g, the wall paper and multi tasking thing. my only concern is that , my phone is so slow now after jailbreaking and unlocking 4.0, any fix? thanks

  29. Xyfzie.

    I was able to jailbreak the Iphone 3g IOS4 useing redsn0w but when I clicked on the Cydia app all of the apple apps that come with the iphone (Safari, Iphone, Phone, Messages, Settings…) were deleted. The Cydia app deleted as well, all I can see now are the apps I have download from Itunes suchs as Facebook and Pandora.

    What do I need to do to fix this problem?

  31. Jonathan.

    This guide worked perfectly. Thanks!!!!!

    note: the cydia icon might appear white to fix:

    1. Open Cydia.

    2. Tap the Manage button on the bottom.

    3. Than select sources.

    4. Tap on the edit button on the top right corner, and then select Add.

    5. Type in http://apt.saurik.com/cydia-3.7

    6. Then Add source.

    7. Reboot the iDevice.

    I just jailbroke my iPhone 3g with 4.0 (6/23/2010) with redsn0w 0.9.5b5-4. So far it’s working flawlessly.

  33. Ashley.

    i just tried it an worked like a charme. I was was even able to unlock the phone aswell with firmware 4.0. The only problem is multitasking doesn’t work properly. Thanks

    I Downloaded Red-snow 0.9.5 for Mac and when I try to open, it says “you cannot open the application Red-snow because it is not supported on this architecture”. Any idea what that means. I am new to Mac and would appreciate any help.

  36. transistor.

    iPhone 3G and iOS 4 jailbroken succesfully.
    Took only a few minutes and then Cydia had to do some cleaning up.
    Redsn0w 0.9.5b5-3 has a checkbox to activate Multitasking and Wallpapers, very convinient and all working fine.
    Thanks for the instructions!

  37. JJ.

    I also tried using the b5 redsnow on an ipod touch 2g, but it wouldn’t recognize the released and final ipsw. Downloaded through itunes and updated the ipod with it, still wouldn’t recognize it as valid firmware.

  38. bartaba_666.

    I jailbreak an ipod touch 2G.
    The multitasking doesn’t work correctly.
    The springboard crash every five minutes and now it just crash totally.
    Most of Cydia applications doesn’t work (sbsettings ; Winterboard).
    I wait for limera1n now.

  39. MonkeyMan.

    Hannes, 2009 models are third generation. Therefore, the regular non-jailbreak iOS4 will work with all iPod touch features. This jailbreak will work also, but there would be no reason to install it. On a separate note, has anyone who installed this on a second generation (late 2008) have any success with multitasking?

  40. Hannes.

    Does this work with an iPod touch 2G LATE 2009…they late 2009 models have the same bootloader as the 3G .. does it work for me?

  41. MonkeyMan.

    Just installed onto iPod Touch 2G. Wallpaper and folders work great; however, multitasking does not work properly. Although there is a bottom bar that shows recently run apps, you are unable to pick up where you left off. This is simply just a history log, rather than the multitasking that was advertised. Switching between apps will cause app to restart and lose active point.

  42. noob.

    What about Ipod touch 2.5G (otherwise known as: MC 3G, or, 8GB 3rd gen) I have one of these, and its jailbreaked with spirit on 3.1.2… Can i do this?
    email me if so! 😀

  43. everybody!.

    hi everyone….

    this is for the final release of ios 4… released on the 21st

    but to jailbreak it you need to select the ios 4 GM version…

    then it will work…

    any other issues keep asking…

  44. Eric.

    I think your supposed to use the beta ios 4 in redsnow.. unfortunately they dont mention which version.. tried beta 4 with same error

  45. Gryphon.

    Oh, I should have let you know that I’m using the Mac version and am attempting to jailbreak an iPhone 3G.

  46. Gryphon.

    Redsn0w 0.9.6 did not recognize the .ipsw firmware file (iPhone1.2_4.0_8A293_Restore.ipsw) that iTunes downloaded today as the update to iOS 4.0.

    Received a message “Unable to recognize specified IPSW.”

    Any ideas anyone?

    1. MuEmpire.

      you have to use the beta 0S4 when you select your CURRENT ispw. meaning you have to update to the beta BEFORE you jailbreak. are you still on 3.1.2 or 3.1.3? i think its the only way it will allow?

    2. Help!!!!!!.

      I need Help too!!! i’ve tried re-downloading the restore software so many times with firefox, chrome, and internet explorer, and i’ve gotten like so many different versions of redsnow… but its still saying “unable to recognise specified IPSW”… what am i doing wrong???
