Thank you for this information. Only one question: in step 2 do you say that need donwload the ipsw file from http://download-ios.com, but I read that the ipsw file is downloaded from the Apple Server (“you are going to download iOS 4.3.1 for 4th Generation iPod Touch IPSW directly from Apple Inc. server”), however, this mean that is the same file that was downloaded from the itunes in the update process, so, why dont use the same file downloaded by itunes? (located in: C:UsersUSER_NAMEAppDataRoamingApple ComputeriTunesiPod Software Updates) – Worked for me :)
step # Download redsn0w 0.9.6 RC9 for Windows (redsn0w_win_0.9.6rc9.zip)
# Download iOS 4.3.1 IPSW file for your device from download-ios.com
I forgot: one final recommendation, in Win7 64bit, execute the Redsn0w.exe file in compatibility windowsxp + administrator mode (right click – properties).
Yes, it's the same file.
Hi,
Could you please tell me that this jailbreak can work with an iPhone 4 (factory unlocked) Version 4.3.1 (8G4), Firmware 04.10.01 or NOT? Thank a lot!
