- Plug your iPad into your PC/Mac and open up iTunes
- Shift-click (Windows) or Option-click (Mac) the “Restore” button in your iTunes iPad device summary page. Find the firmware that you’ve downloaded, and restore.
- After this is complete, iTunes will ask you if you want to set up your iPad as a "New" device, or from a previously stored backup. If your goal is to return to a life before jailbreak, you’re probably going to want to restore.

Undo, Unjailbreak iPad (Ctrl Z)
Since it was just announced that iOS 4 is now available for the iPad, many of your will be interested in un-jailbreaking your iPad in preparation for this update. If Apple will be handling your device for any reason, you should probably unjailbreak it to maintain your warranty as well!
Even though iOS 4.2.1 jailbreak is possible via Redsn0w 0.9.6b2, but Cydia needs an update and is still broken which makes jailbreaking your iPad pointless for many.
iOS 4.2.1 offers a lot of new features to those still running an iOS 3.2.X version in a jailbroken state. Check here for instructions to return your iPad to it's unjailbroken state...
NOTE: This guide will only work if you saved SHSH blobs for the firmware you downgrading toward.
All you need is your device’s latest firmware file, and make sure you’ve backed up—you’re going to lose everything.
