A) Did you save the SHSH for 4.3.3? If you haven't, then it's too late. You wouldn't be able to revert back once you upgrade.

B) It's against the rules of this fourm to ask for / give help with Installous apps.
 
I did not, but I'm still on 4.3.3. I wanted to get this all figured out before upgrading on the 12th. As for the second question, that is understandable, and I apologize.

The fact that you are still on 4.3.3 doesn't help you save SHSH for it. SHSH are issued by Apple. Since Apple is no longer issuing SHSH for 4.3.3., there is no way for you to save it. Sorry.
