was worried about the hole thats used to make the jailbreak work, but when checked RedmondPie later seen that there is the PDF warning to install from Cydia, so guess it could be safer with the jailbreak than withoutTo the best of my knowledge there is no jailbreak for 3.2.1 except the Safari-based JB. I doubt there will be anything new until the next major firmware revision (they have to use the exploits they find very sparingly).
What are you worried about, exactly?
I'm not sure why you're saying this and why you title it "Important!". I think you're introducing fear, uncertainty, and doubt with that posting.just keep 3.2 and then use the PDF patch from cydia!
