Important

  • Sn0wBreeze 2.3 is still in beta, Updating to iOS 4.3 is not safe as the mobile substrate conflict is not corrected yet Mobilesubstrate is fixed now.

  • If you depend on unlock, don’t update to iOS 4.3 because there’s no unlock out yet. UltraSn0w is broken on iOS 4.3 even if your Baseband is preserved. UltraSn0w has been fixed for iOS 4.3 in Sn0wbreeze.
  • Sn0wBreeze is available for Windows OS only.

Step 7

Now follow the on screen instructions to put your iDevices into Pwned State. Sn0wBreeze instructions are important to follow because this will put iDevice into Pwned DFU state NOT the simple DFU mode.

  • Hold Power + Home buttons for 10 seconds
  • Now release the Power button but keep holding the Home button for 10-30 more seconds
  • Your device should now be in DFU mode

Sn0wBreeze will prompt you once you’re into Pwned DFU state.

Step 8

Now open iTunes, Hold down the Shift key and hit the Restore button.
Browse and select the custom firmware that we just created, from the desktop.

iTunes will start restoring iOS 4.3 on your iPhone/iPad/iPod Touch. Once the restore process is complete, your device might stuck at the Apple logo. Don’t panic, follow the next step.

Step 9 – Booting in Tethered Mode

Like I told you earlier, it’s a tethered jailbreak.

On your desktop, there’ll be a new folder named iBooty-for-4.3. Open the folder and run the iBooty.exe.

Select your device from the drop down menu (bottom-right) and hit the start button.

Follow the on screen instructions to put your iDevice into DFU mode.

  • Hold Power + Home buttons for 10 seconds
  • Now release the Power button but keep holding the Home button for 10-30 more seconds
  • Your device should now be in DFU mode

Once you’re into DFU mode, iBooty will do the rest and your iPhone, iPad or iPod touch will boot into jailbroken state!

It looks like people can jailbreak iphone easily now, but not unlock …wow

Srikanth4285 March 14, 2011, 8:58 am

its an untethered jailbreak, you can restart your iPhone/iPod/iPad without using iBooty, but to use Cydia & Jailbroken apps you need to boot with iBooty.

PCman13 March 27, 2011, 8:38 pm

WRONG!!! This is called semi-tethered. As you said, Cydia won’t work without ibooty. Untethered means: no programs like ibooty needed, just power on your device, and it works, even Cydia.

andrew March 29, 2011, 11:43 pm

It is untethered for the iphone 3gs old bootrom though, which I have.

Apple666 March 15, 2011, 2:49 am

It works poorly, don’t recommend it!
1/5!

Luke March 15, 2011, 10:40 am

Sn0wBreeze 2.3b1 provides a tethered jailbreak. You will need your computer every time you reboot for it to work.

WRONG INFO THIS ONLY APPLES TO NEW BOOTROMS NOT 3Gs with old bootroms
