Then do you think Apple does this to jail escaped ipad's?
Not white, not black just passionate shades of grey...

What we did have was a jailbreak PDF warning application that you could install over the jailbreak that would give you a popup window to remind you of the PDF exploit so that you would have a chance to reconsider the PDF you were about to view in a URL or download.
The only thing that 3.2.2 does is remove the PDF exploit. Since they deliver the entire firmware every time there is a change, then it will remove your jailbreak, and since the jailbreak is based on the PDF exploit, it will not be possible to re-jailbreak using the popular method of jailbreakme.com.
What I meant to say was that if your iPad was jailbroken and you performed the 3.2.2 update, the jailbreak would be removed and you would be left with an iPad 100% the way Apple intended it. Every time you do an update / upgrade from Apple, it wipes out the jailbreak if there was one.
As far as not seeing any difference, you won't. The update was to "fix" a security issue with the Safari browser. There were no other "kewl" features added with this update. Those will come with iOS 4.? (whenever that is!)
Will anyone even bother to find a new exploit until 4.0 is released I wonder? If they find one I think they should hold back, hoping it can be used on 4.0 instead.
