He really can't update to 4.3.3 firmware as Apple has stopped signing it... He would have been able to update to 4.3.3 if he would have saved SHSH blobs on Cydia server... But to do that one needs to be on 4.3.3 firmware but unfortunately OP didn't update to 4.3.3 when he had a chance... So now he either have to stick to 4.3.2 which can be jailbroken or update to 4.3.5 and live with tethered jailbreak...
Editing host file should solve it right
