아래 내용은 9월 29일 새벽 12시부터 3시 30분경까지 지인과 개삽질을 하며(전화통화/메신저챗) 함께 시도했던 것인데 결론은 안됩니다.... greenpois0n 완탈을 기다리세요.


6. host
hosts 파일에 아이피(도메인) 셋팅 후 가능합니다.^^
즉, cydia 서버로 연결하여 복원이 가능합니다. 
복원 (shift + *.ipsw) 선택 전에 hosts 수정해 주세요.
c:\windows\system32\drivers\etc 폴더 안에
hosts 파일의 맨 아랫줄에 
74.208.105.171 gs.apple.com 을 적어 넣은 후 저장하고 끄면 됩니다.
or 74.208.10.249 gs.apple.com


I can confirm that my iPad (3G, 64GB, iOS 3.2.2) can be downgraded to iOS 3.2.1 without doing anything (such as saving its SHSH) before. 

I summarized the steps I took. Hope that this will make the whole process easier to follow.

Preparation:
1. Download 3.2.1 firmware (use the link in the 1st post).
2. Download "umbrella" application (see the 1st post or google for it).
3. Make sure your iTunes is the latest version.
4. Connect your iPad and let iTunes syncs it with your computer (you will want to restore your data after downgrading).

Downgrading process (more info for each step below):
1. Start "umbrella" and save SHSH blobs of your iPad.
2. In "umbrella", click Start TSS server.
3. Put the iPad in recovery mode.
4. In iTunes, hit Shift + click Restore.
5. Select 3.2.1 firmware, and wait until the restoration finishes.

Step 1:
1. Use the Advanced options to make sure that Device field is correct and Request From field is Cydia.
2. It should report "successful" after a while.

Step 2:
1. Using the TSS server saves you from changing the "hosts" file, if you have read about the need of this change elsewhere.

Step 3:
An iPad can be put into recovery mode when it is connected to a computer with the sync cable. This state, which your iPad is already in if you didn't disconnect the iPad after steps 1 and 2, can be achieved by the following two steps:
1. Connect iPad to a computer
2. Wait for sync to finish.
Now, to put the iPad into recovery mode:
1. Push both the home button and the power button until the logo of a cable connected to iTunes shows up.
2. You should get a message box from iTunes on the computer saying that the iPad is in recovery mode.

Steps 4 and 5 are as straight as they are.

Jailbreak iPad running iOS 3.2.1:
1. On iPad, run Safari to www dot jailbreakme dot com.
2. Follow the easy instructions on the site: "slide to jailbreak", "Sit tight", and so on.
3. After the jailbreak process has done, Cydia app has been installed also (on one of the screen). Use it just like using the App Store app.

Thanks for the other posts and have fun.
