I bought an Ipad 2 GSM which was on 4.3.3, so I had the chance to jailbreak it with jailbreakme, and I did it. After two days I had to restore it, and I installed 4.3.5. I tried to downgrade the device, but tinyumbrella says that the only shsh saved for my ipad is the 4.3.5 shsh. Is it possible that Cydia hasn't saved my SHSH for 4.3.3?
