    Paiboon…. the process is to help jailbreak the firmware 4.0.1 if you still look into your setting after the jailbreak you still see 4.0.1..
    since redsn0w is older then the firmware 4.0.1.. uploading the ipsw 4.0.1 wouldnt be recognize. but its firmware is very close as to the 4.0 os.

    If anyone is interested, i just did this and it kept my IOS at 4.0.1 im assuming that the redsn0w just gets tricked into thinking its 4.0. but worked like a charm

    Hi! I got a question. Could I jailbreak my iPhone 3GS by your Redsn0w instructions that you’ve gave it for us at this page? Or it’s only work with iphone 3G?

    its simple the iso4 and ios 4.0.1 r the same just update to fix whatever but when u update phone with ios 4.0.1 thats the firmware u have on yr phone if yr not sure do the jailbreak then go on the phone setting–general–about and u should see ios 4.0.1

    It seems to me that we need to restore with 4.0.1 and then use redsn0w with 4.0….. did I get that right?

  16. LMA July 18, 2010 Reply

    Uh… where does 4.01 come into play? Why do I even need to download 4.01 if I’m letting redsn0w use 4.0?

    Anyone else get this?

    You have to update your phone to iOS 4.0.1 first before rejailbreaking it. It is the same process that was used for 3.0.1.

    we have downloaded the ipsw file for 4.0.1 firmare for iphone 3g and it does not load the file is not recognised how do you make the firmware work plz

  19. Ed July 17, 2010 Reply

    In step 2, when browsing 4.0 firmware folder, there is no IPSW file to select.
    Please help

    You should upgrade your software from 4.0 to 4.1 via iTunes first, right? For this, you would use the iPhone1,2_4.0.1_8A306_Restore.ipsw from the download link provided above.

    Im sorry spelling correction: 4.01 would be the currently installed firmware.

  22. Trygger July 17, 2010 Reply

    No it wouldn’t be the same firmare (4.0) simply because Redsn0w does not use itunes to restore the device. in other words: The firmware you have currently installed on the device is only being modified by the Redsn0w program and adding Cydia onto it. So if you were to select a 3.0 firmware in Redsn0w it would give you a 3.0 jailbreak with 4.0 as the actual firmware on the device. Not sure if that is even possible(because of incompatibility) but it seems logical.

    Paiboon ur not Restoring with 4.0 Firmware u will restore ur device wid 4.0.1 but after that u have to apply this trick for jailbreaking ur device 3g iphone Redsnow will not recognize 4.0.1 but it will recognize 4.0
    thats all

    I am using a new i phone 3gs which i bought last week frm Qatar n it accepts any sim card so i guess its ‘unlocked’. unfortunately wen i connected the phone to itunes for the very first time, it asked me if i wat an upgrade to ios 4.0 n i accepted it, which turned out to be a big mistake cos i was not aware of the ‘jailbreakin’ process.. i read some blogs n all n wat i cud find was that i need to have some SHSH saved before upgradin..
    is this methos u explained applicable for me?

  25. Paiboon July 16, 2010 Reply

    You said “when redsn0w ask you to select firmware, browse to iOS 4.0 ipsw instead of iOS 4.01” then in this case the actual firmware in iphone would be 4.0 and not being 4.01, isn’t it?

    Or how the firmware of iphone will become 4.01?

    Please advise.
