With the PwnageTool bundles, you could jailbreak iPad 4.3.1 iOS. Two things to note here are that this is a tethered jailbreak process and you will need the Mac OS X as PwnageTool works only on that. But if you are a Windows user, don’t worry because tools like Sn0wbreeze, GreenPois0n etc could be used to jailbreak iPad 4.3.1 iOS on Windows after a new version of them are released.
So, stay tuned to Tips Needed as we will come up with the guides to jailbreak iPad 4.3.1 iOS on Windows.
Now, we can back to the topic. If you are a Mac user, you will be able to do this jailbreak. But I am repeating once again, this is a tethered jailbreak. So you will have to use tetherboot on every reboot of your iPad once it is jailbroken on iOS 4.3.1, if you want to keep the jailbreak.
Below are the steps to jailbreak iPad 4.3.1 iOS using PwnageTool bundles :
3. Download the PwnageTool bundle for iPad iOS 4.3 from here.
4. Now, follow the instructions from steps 4 to step 12 given here(use iPad, its firmware and the bundles where ever needed).
5. In the tetherboot instructions, instead of kernelcache.release.n90 and iBSS.n90ap.RELEASE.dfu, use kernelcache.release.k48 and iBSS.k48ap.RELEASE.dfu. Take care to replace them in the commands too!
That’s it! You have jailbroken your iPad 4.3.1 iOS. It’ll be ready after the reboot.
