This tutorial will show you how to jailbreak and unlock your 2G iPhone. It has been updated for the 2.2.1.
You need iTunes 8.0.2 to continue…Â
You will also need the 2.2.1 iPhone firmware.Â
2.2.1 (2G):Â iPhone1,1_2.2.1_5H1_Restore.ipsw
When downloading the IPSW file, it is best to download it with Firefox!
Create a folder on your desktop with all the required files listed above.
You will be brought to the “Browse for IPSW” page. On my laptop, it automatically found the IPSW. If PwnageTool doesn’t automatically find the ipsw file you can clickÂ Browse for IPSW…Â button.
TheÂ GeneralÂ settings allows you to decide the partition size. Click activate the phone and Disable partition wipe-out. Click the blue arrow button.Â
***If the Enable Baseband checkbox is not greyed out, checkmark it. This will allow the unlock to occur!***
***For the 2.2.1 firmware you may have to increase the size of your root partition slightly for the IPSW build to be successful. 590MB worked just fine for me***
In theÂ BootneuterÂ settings, click Neuter bootloader, Unlock baseband, and Auto-Delete BootNeuter.app. It is not necessary to upgrade the bootloader unless you are really feeling the need to be on 4.6. Click the blue arrow button to continue.
Click to select theÂ Download packagesÂ tab. Then click theÂ RefreshÂ button to display all the available packages. Double clicking the package you want will download it and make it available in theÂ Select PackagesÂ tab.Â
Click the blue arrow button to continue.
***: After loading the 4.6 BL you may be asked if you’re a legit user. If you legally have ATT or an iPhone plan in a different country, clicking yes will not unlock the iPhone and activate it as your legal plan already activates it and there is no need for an unlock. However if you wish to keep the iPhone unlocked, when asked if you’re a legit iPhone user, click no
Be ready to follow directions now. It will ask you to hold the home button and the power button for 10 seconds. Then, you will have to release the power button and hold the home button for 10 seconds to enter DFU.
IMPORTANT***: If you have Mac OS X 10.5.6 you may have an issue with putting your iPhone into DFU mode. The easiest option is to use a USB hub between your iPhone and the computer. Another option is to runÂ thisÂ automator script. NOTE*: Make sure the script completes properly. If the files are not replaced properly you will lose keyboard and mouse upon reboot. Later today we will post a third alternative for enabling DFU mode on your Mac.
Navigate to theÂ PwnageÂ folder on your desktop using the dialog window that appears. Select the custom IPSW that was created (iPhone1,1_2.2.1_5H11_Custom_Restore.ipsw) and click theÂ Openbutton.
Once the restore has completed, it will restart your iPhone. The phone will then launch BootNeuter.app to unlock your device.
Please allow 5 minutes for this to complete. Your iPhone will restart once completed.
