Jailbreak iOS 4 on iPhone 3GS

iPhone Dev Team had released PwnageTool 4.01 to allow iPhone 3G and iPhone 3GS (old bootrom) users to update and jailbreak their iPhone with iOS 4.

Yesterday, we had published our step-by-step guide to jailbreak the latest iOS 4 using PwnageTool 4.01 for iPhone 3GS users. This guide is for iPhone 3G users. 

Some important points before we proceed:

  • Please note that jailbreaking your iPhone or iPod Touch may void your warranty and hence proceed with caution
  • Do not forget to backup your iPhone before you proceed. You can refer to this post for instructions on how to backup your iPhone 3G.
  • After the jailbreaking process is complete, do not forget to checkout our article on tips to keep your iPhone secure. Also, remember to change the password of your jailbroken iPhone
  • PwnageTool is only supported on Mac OS X and is not supported on Microsoft Windows
  • PwnageTool does not unlock your iPhone 3G. You can use Ultrasn0w to unlock your iPhone after you have successfully updated and jailbroken your iPhone 3G with iOS 4.
  • This guide is only for iPhone 3G users, iPhone 3GS users can refer to this step-by-step guide.
  • If you have a jailbroken your iPhone 3G running iPhone OS 3.1.2 (but not jailbroken with Spirit) then you should create the custom firmware file (.ipsw) with PwnageTool 4.01 and restore from recovery mode or DFU mode.
  • If you have an out of the box iPhone 3G you should restore using a custom iPhone firmware file created using PwnageTool 4.01 using DFU mode (using PwnageTool).
  • If you have a jailbroken iPhone 3G running iPhone OS 3.1.3, it is very possible that this can fail from recovery mode. If it fails then you will need to restore using DFU mode (using PwnageTool).

If you meet the requirements mentioned above then you can proceed with the step-by-step instructions to jailbreak your iPhone 3G.

Step 1: Download PwnageTool 4.01 from here or here and save it in a folder named "Pwnage" on your Mac desktop.

Step 2: You also need to download the iOS 4 firmware file (iPhone1,2_4.0_8A293_Restore.ipsw) from this link. Download the file using Firefox since Safari might auto extract it.
