Hi ... Recently i purchased an 8gb Iphone with firmware 1.1.1 on it .. I followed the instructions and i downgraded my phone to version 1.0.2 ... I jailbreaked it, activated it but i can't unlock it even everything is said to be ok ( even "unlock" says that it has completed the process after 20 minutes ) ... I put my own sim card in it I get a "sim locked" message, and when I put my pin to unlock it, my iPhone says that my sim card is incorrect .. Can anyone help ?? PLEEASEEEE !!!
