    Did you successfully downgrade it to 4.3.3 though? And iPad 2 can only be jailbroken via so using Redsn0w is completely useless for you.

    Your downgrade needs to happen in iTunes, not Redsn0w. The only way to downgrade is to have SHSHs for 4.3.3 or you won't be able to. You need to check with TinyUmbrella ( for SHSHs for 4.3.3.
