How to Jailbreak iOS 4.3 Using Snowbreeze 2.3 on iPhone, iPad and iPod Touch [Guide]

Earlier today we reported that Sn0wbreeze 2.3 has been released by iH8sn0w. Sn0wbreeze 2.3 can jailbreak iOS 4.3 on iPhone, iPod Touch and iPad but the jailbreak is tethered boot at the moment meaning you have to connect your device with PC to get jailbroken state on it.

The complete step by step guide to jailbreak your idevice using Snowbreeze 4.3 is posted after the break.


  • Ultrasn0w doesn’t work on iOS 4.3 yet. So if you rely on unlock, don’t update your device to latest iOS 4.3 version until iPhone Dev Team comes up with a working ultrasn0w.
  • Sn0wbreeze is based on Windows OS. Mac users can use PwnageTool to jailbreak iOS 4.3. Head over to this post for complete PwnageTool Jailbreak instructions.
  • Before updating your device to iOS 4.3 make it sure you have saved SHSH blobs for iOS 4.2.1 on Cydia Server so that you can downgrade iOS 4.3 to  4.2.1 any time.

Step 4: Snowbreeze will identify the iPSW file at this stage. Click on arrow again to proceed.

This will make iTunes prompt you to select the location for iOS 4.3 which you have already downloaded in Part 1.

Booting Tethered

As we have told you iOS 4.3 jailbreaking is tethered at present, so you have to connect your device with PC and use iBooty to get jailbroken state. Run iBooty, which is extracted on Desktop after cooking custom iOS 4.3 using Snowbreeze.

Select your device and again enter DFU mode by following the onscreen instructions. Soon iBooty will do its work and your device will be booted in tethered jailbroken mode.

Now tap on Cydia icon and install your faviourite apps and tweaks from Cydia Store.
