If someone could help me that would be greatly appreciated. I have pawned my 1g iphone before to 2.0 and worked but the phone was sluggish so i tried to repawn custom to get rid of cydia and know i get the 1600 error. So i pawned again using simple mode and still get the error, my phone is in dfu mode and i am using the custom ipsw created. What should i do to get my phone pawned again?
