The following are instructions on how to jailbreak iOS 4.3.3 using JailbreakMe 3.0 for the iPad 1 and iPad 2. This is an untethered jailbreak.
Prerequisites for Jailbreak
This jailbreak is performed on the iPad itself. No computer is required. Ensure that you have adequate battery levels and an active Internet connection.
It is recommended that you update the iPad to the iOS 4.3.3 firmware although the jailbreak will work on all 4.3.x versions.
Save SHSH Blob Recommendation
For this particular jailbreak, it is highly recommended that you save your SHSH blobs as Apple may release iOS version 4.3.4 very soon and stop signing the current 4.3.3 firmware. Not sure what we’re talking about? Read more here.
iTunes Back Up Instructions
While an iTunes back up is optional, we highly recommend it. This is to allow you to restore to your back up in case anything goes wrong while you perform the jailbreak.
Open iTunes on your computer and connect your iPad via the supplied USB cable.
Once your iPad is detected, right-click your iPad from the menu on the left and select ‘Back Up’. The process should take approximately 5 minutes or more depending on how much syncing needs to be done. The back up status can be tracked via the top progress bar in iTunes or from the status on your iPad. Once complete, we can move on to the actual jailbreak.
On your iPad, open up ‘Safari’.
In the address bar, type in “www.jailbreakme.com” and tap on ‘Go’.
Alternatively, if you are reading this from your iPad, you can click on this link.
Tap on ‘FREE’ followed by ‘INSTALL’.
Safari will automatically close and you will be brought back to the home screen. You should now be able to see a Cydia icon with a progress bar on one of the pages on your home screen indicating the status of the download+install process.
When you see just the Cydia logo, that means you have successfully jailbroken your iPad. If for some reason the jailbreak failed, try repeating the whole jailbreak process a few more times.
Open the Cydia app. Tap on ‘User’ followed by ‘Done’.
You will be brought to Cydia’s home screen. At this point, you will see a black bar status bar on top indicating that Cydia is downloading packages and releases, etc. Do not ‘Cancel’. Allow a few minutes for this to complete before starting to use Cydia.
PDF Patcher 2 Instructions (IMPORTANT)
One last thing you should do before you go off happily with your jailbroken iPad. You need to close up a security vulnerability.
JailbreakMe 3.0 takes advantage of a PDF exploit which unfortunately also leaves your iPad vulnerable to malicious attacks. The fix is simple:
In Cydia, tap on ‘Search’.
Type in ‘pdf patcher 2′ in the search bar on top and tap on the ‘PDF Patcher 2′ result.
Tap on ‘Install’ followed by ‘Confirm’.
Once the installation is complete, tap on ‘Reboot Device’ to complete the patch. The reboot will take a few minutes.
We hope your jailbreak was a success.
