I am now 99% sure that my first mistake was upgrading to 4.0 a few days before Pwnage was released. Obviously, I can't restore to a custom firmware made by Pwnage, I just get the spinning wheel in iTunes and then it gives some error. I have downgraded to 3.1.3 and Jailbroken but the buyer also wants it unlocked. I am correct that because I upgraded to 4.0 and the BR was upgraded that I can now not unlock this phone running 3.1.3? Thanks I got a feeling I have to refund some money in the morning.
