It is a new and modded PwnageTool that jailbreaks iPad and brings Cydia back to life on iOS 4.2.1. However there is one disadvantage with this tool (with all jailbreak tools for iOS 4.2.1 till iPhone Dev Teams comes up with a new solution) that it provides tethered jailbreak which means you’ll have to connect to PC every time to put the iPad into jailbreaked state.

PwnageTool allows you to restore to a custom IPSW file. For instance, you can restore to a pre-jailbroken firmware while simultaneously maintaining your current baseband (and thus your ultrasn0w carrier unlock). You can also add whatever packages you want in the “Expert” mode of PwnageTool, if you wish to pre-install Cydia packages. iPhone 3G users get the additional benefit of selecting their own boot and recovery logos, and features like multitasking and battery charge percentage.

ULTRASN0W UNLOCKERS BEWARE!! ULTRASN0W UNLOCKERS BEWARE!! The biggest mistake you can make (and it is a big one!) is lettings iTunes restore to the official IPSW — you’ll lose the unlock and won’t be able to go back! You must use Option-Restore, not just the Restore button by itself. Then navigate to your custom IPSW — not to the stock one! If you accidentally started a restore to the official IPSW, unplug your iPhone immediately before the restore gets to the “Updating Firmware” step!

It is to remind you PwnageTool works on Mac machines only. Windows users will have to wait a little longer because iH8snow is working on Snowbreeze 2.1.
