    Error 20 is mismatch in cryptokeys or in other words failed jailbreak. You need a clean install of the iPhone OS. That is usually the case. In rare instances it can be linked to failure in USB communications.

    I have a fresh install of iOS 4.3.5 on there and it still says it. I have never jailbroken this phone before. Any other tips?
