How To: Jailbreak iOS 4.0.1 On iPhone 3G/3GS With Redsn0w Beta 5

Finally the iOS 4.0.1 is released by Apple and seemingly this release only fixes the signal bar display. One good thing about this release is that it doesn’t change the baseband of your iPhone meaning that you can jailbreak iPhone 3G/3GS on iOS 4.0.1 with Redsn0w 0.9.5 Beta 5.


Here are the step by step instructions on jailbreakingiOS 4.0.1 on iPhone 3G using RedSn0w 0.9.5 Beta 5:

  1. The first step is to download the iOS 4 firmware for iPhone 3G/3GS. Although this procedure will jailbreak iOS 4.0.1 on iPhone 3G/3GS, but still you will need iOS 4 firmware.
  2. Now update your iPhone to iOS 4.0.1 using iTunes 9.2.
  3. Now once your phone is upgraded to iOS 4.0.1 launch RedSn0w on your computer and press the Browser button to navigate to the iOS 4.0.
  4. Click “Next” after IPSW verification is completed by RedSn0w. Now select Cydia and other options that you want to install and press Next.
  5. Now power off your handset and connect it with your computer.
  6. After you have made sure that your phone is properly powered off and plugged into computer, put your phone in DFU mode.
  7. Now sit back and relax as redSn0w will take care of the installation and jailbreak.

Once the installation is complete, reboot your phone and there you go! you have successfully restored your iPhone 3G/3GS on iOS 4.0.1 with jailbreak.

Update: We tested this procedure on iPhone 3G and we got “tipped” that this also works for iPhone 3GS. It is now clear that this procedure is not applicable on iPhone 3GS and thanks to all our friends who pointed this out.

  1. lol, Author seems to have no idea what he is writing, from when did Redsn0w started jailbreaking iPhone 3GS ??

    Also Redsn0w 0.9.5 Beta 5 can only jailbreak iPhone 3G or iPod Touch 2G 4.0.1 non-mc model. Get your facts clear before writing post.

    if you follow this post then your iPhone 3GS will get locked.
