how to downgrade to 4.3.3

[adilmk123]

I know the answer is simple but my case is complicated.

i was on ios 4.3.3 bb 4.10.01, I preserved my bb and upgraded to ios 5.0. Right now i am using ios 5, bb 4.10.01 but tethered jailbreak.

Now the issue is that i would like to downgrade back to 4.3.3 as tethered jailbreak is pain in as*.

I do not have the SHssh(whatever it is) saved.

Now tell me what is the procedure to downgrade it to ios 4.3.3 while preserving my bb 4.10.01.

Thanks

No u cant downgrade to 4.3.3 if u haven't save shsh blobs on cydia
and also apple not singing in 4.3.3 version but u can downgrad to 4.1
