Step 1: Download and install the latest version of iTunes.

Step 2: Now start iTunes and sync your iPhone with your PC so that it backs-up all your important data including settings, apps, music, contacts and photos.

Step 3: Download Sn0wbreeze 2.0 and the original iOS 4.1 firmware file (download links at the end of the page). Move all these to your desktop.

Step 4: Start Sn0wbreeze and select “Simple Mode” for easy process.





Step 5: Sn0wbreeze will ask you to locate the .ipsw original firmware file. Point to the correct iOS 4.1 file by clicking on “Browse” button. Sn0wbreeze will verify the selected file and then will present you with following screen.



Step 6: Click on "Yes" when Sn0wbreeze asks you “Do you want to activate your iPhone?” for hacktivation. Click on “No” only if you are on an officially supported carrier like AT&T.

Step 7: Sn0wbreeze will now create custom firmwares for your iPhone which is jailbroken, (Save it on your desktop)


Step 8: Now Download iReb V4.0 (links at the end of the post) and make sure that iTunes is launched

Step 9: (This step for iPhone 3G, and iPod touch 2G [MB] only) Launch iReb (to bypass iTunes errors) and choose “Online Mode” then choose your device




Put your iPhone in DFU mode by following this step:

* Turn iPhone off.
* Hold Power and Home buttons together for 10 seconds or so.
* Release Power button but keep holding the Home button until your computer recognizes a new USB device.
* iTunes will now recognize your iPhone



Step 10: Now, You will have to restore your iPhone to the jailbroken custom firmware by Clicking on the iPhone icon on the left sidebar of iTunes then hold left “alt” button (“Shift” button on Windows) on the keyboard and then click on “Restore” then release the alt button, Now Select the custom firmware created by Sn0wbreeze and Let iTunes go in a bunch of steps.

Step 11: Sn0wbreeze doesn't upgrade your baseband and will never do, so you can use Ultrasn0w 1.0 to unlock your iPhone by following the step by step guide posted here.
