(NOT 100% SURE) Open tiny umbrella under advance look and see if option about shsh from cydia is checked. Then try get SHSH blobs again. Look in the Log tab. It should tell you if you have/haven't got it saved.
From what I understand is apple stop signing 4.3.3 so there will be no way to save it if it's not already saved.
Another option you can try is iFaith and see if you can get it.
