How To: Jailbreak the iPhone/iPod Touch/iPad/Apple TV 2G Running iOS 4.3.1! [The PwnageTool 4.3]

Step 1) – The first thing you will need to do is download the PwnageTool to your Desktop (Click the download link below).
Download PwnageTool 4.3 (Not working? Click here)
Note: The PwnageTool tool is only
available for the MAC OS X operating system. If you have Windows, it is
possible to run the PwnageTool but only via VMWare
(we may make a tutorial on how to do this at a later date). Please
follow our RedSn0w 0.9.6rc9 how to guide which will show you how to
jailbreak the iOS 4.3.1 firmware untethered for Windows by clicking here.

Step 2) – Once you have downloaded the PwnageTool,
you are going to need to now run it. Once the PwnageTool is up and
running, click okay to the pop-up window. Now if you have never used the
PwnageTool you will notice there are many options presented to you. We
will guide you through to process so do not get overwhelmed. The first
thing you must do is click on the expert mode button in the top left
hand corner of the screen (you will notice by default, Simple mode is
selected, but we want Expert mode).




Now once you ensure Expert mode is selected, you will need to select
the iDevice you are going to jailbreak, once you do select your iDevice a
big check mark will appear over the one you selected. Click the Blue
Arrow to continue…
Step 3) – In the next screen you will be selecting the iOS 4.3.1 firmware that corresponds to the iDevice you are jailbreaking.





Mac OS X Note: Your iDevice’s firmware files are stored in the following directory:
<blockquote>

~/Library/iTunes/iPhone Software Updates

</blockquote>
Once you have selected your firmware file, please click the blue arrow to continue…
Step 4) – Once you have clicked the blue arrow you
should be at a screen with several options. It is from this screen you
can go through the process of customizing your jailbreak.




Here is a quick breakdown of what each of the tabs customize:
General Settings: From here you can customize
features of your jailbreak such as root partition size (the amount of
space dedicated to jailbroken apps), activation options for those of you
using an unofficial carrier on your iPhone and you can also re-enable
functionality for those on you jailbreaking older iDevices. Unlockers only: Ensure you click the activate the phone option if you are using an unofficial carrier on your iPhone.
Cydia Packages: In this area you can select Cydia packages to be pre-installed when you restore the custom firmware file to your iDevice.
Custom Packages: The only thing you need to ensure you do in this area, is that Cydia is selected to be installed.
Once you are done customizing your jailbreak, you will need to go back to the main screen and click the build button.





You will then need to select a directory to save your custom firmware
file to. Once you do this you simply need to wait for it to build. This
can take a few minutes…





Step 5) - Once you have built your custom IPSW, you
will need to put your iDevice into DFU mode so that you can restore this
custom IPSW to your iDevice (through iTunes).
Follow the on-screen instructions that the PwnageTool presents to you:

• Turn your iDevice off
  
• Hold Power and Home buttons for 10 seconds
  
• Now release the Power button but continue holding the Home button for at least 10 more seconds
  
• You device should now be in DFU mode
  

Step 8 ) - Once your iDevice is successfully in DFU
mode, iTunes should pop-up saying your iDevice is in recovery mode (it
is actually in DFU mode), iTunes will also prompt you to restore your
iDevice.





Hold down the OPTION button and click on the restore button, you can
now browse and select your custom firmware file you created. Once you
have selected this firmware file, simply wait for it to be restored on
your iDevice.
Note: Ensure you do not do anything to disturb your iDevice, while iTunes is restoring the custom iOS 4.3.1 firmware file.

Once your iDevice has been successfully
restored to the custom iOS 4.3.1 firmware, you should notice your
iDevice is now jailbroken untethered on the iOS 4.3.1 firmware (Cydia
should be on your SpringBoard). Please leave any questions or comments
