Lots of instructions exist for restoring back to factory defaults, but they fail to deal with the fact that only 3.2.2 is out now. My ipad is on 3.2.1 and jailbroken, and I saved my SHSH 3.2.1 to Cydia, but if I follow all the existing instructions (including modifying my hosts file), iTunes will Still attempt to install 3.2.2 to my ipad. Here's how to get your ipad back to a clean 3.2.1, assuming it is currently on 3.2.1 and you want to simply clean it up (I buggered around so much with mine I killed my wifi). These instructions are for a PC, but no far off what you'd need to do for a Mac. 0. Download an image of iPad 3.2.1 1. Install TinyUmbrella. Read and follow the ReadMe. Basically, update your hosts file to redirect gs.apple.com to 22.214.171.124. 2. Plug in your ipad to your PC. Close Itunes. 3. Run TinyUmbrella. It should detect your ipad. 4. Tick the Advanced Options box. 5. Change the "Request Version" to iPad 3.2.1 or iPad3G 3.2.1. 6. Click "Save my SHSH". 7. Click on "Start TSS Server". 8. Run iTunes. It should detect your ipad. 9. Click on your device in itunes. 10. Shift-click on the Restore button. This brings up a dialog box. 11. Navigate to where you saved the 3.2.1 image from step 0. 12. Confirm that you want to restore your ipad. It will now re-flash your ipad back to a virgin 3.2.1 system. From here, do whatever you want - restore your apps, reconfigure it, jailbreak it, etc.
