Step 1: Back up your iPhone.

It is very important that you perform a backup of your iPhone. When you backup your iPhone, you store your contact information, pictures, music, apps and other valuable stuff on your computer or Mac. In case something goes wrong, it also gives the option to restore the iPhone.

Step 2: Jailbreak your iPhone 2G

Jailbreaking is the first step you need to do to eventually unlock your iPhone. When you jailbreak, we remove the restrictions imposed by Apple in terms of what apps, themes or tweaks you can install and run on your iPhone. With a jailbroken iPhone, you do not lose any existing functionality. You just gain the ability to do more. The best part, jailbreaking is reversible where you can undo the jailbreak by restoring from your iPhone backup. So, make sure you do step 1.

  • Enable Wifi on your phone
  • Open Safari and go to jailbreakme at
  • Once at the website, you will see the screen below.
  • Just slide and initiate the Jailbreak process. That’s it! Your iPhone is now Jailbroken.

Step 3: Update Cydia

The App that will help us to unlock the iPhone is called Cydia. It is a simple iPhone app manager and will get the stuff we need to unlock the iPhone 2G.

  • Once the unlock process is done, launch Cydia
  • Once in there, Cydia will try to look up any updates. You want to make sure Cydia is up-to-date with all the packages.
  • So, install any updates that are missing. Make sure it has the BigBoss repository in there when you are updating Cydia
  • Once, Cydia is done updating, close out Cydia.

Step 5: Install BootNeuter to begin iPhone Unlock process

Now that Cydia is up-to-date, we need to install an app that will actually do the unlock process for us. In order for us to unlock the iPhone 2G, we need to do something called flashing the bootloader and also flash the baseband. Once this is done, you can start using your unlocked iPhone.

  • The app that will do the unlock process is called BootNeuter
  • Launch Cydia and search for BootNeuter app
  • Press Install. You will be asked to confirm that you want to install BootNeuter
  • Once the installation process is complete, you can return to Cydia. However, press the home button now.

Step 6: Configure BootNeuter
This is the last step to finish the iPhone unlock process. We now need to configure BootNeuter to flash the iPhone bootloader and the baseband.
  • Now, look for and launch the BootNeuter app
  • It will automatically detect certain settings like change the version to 4.6
  • Also change the “Neuter” option to ON under Bootloader
  • Under Baseband, change the “Unlock” option to ON as well
  • Press the Flash button. You will be asked to confirm. Press “Flash It!”
  • It will take couple minutes. Once BootNeuter is done, you will get a message saying that your iPhone baseband and bootloader were successfully flashed.
