Hi, I virginized and restored my iPhone to 1.1.1 but I can't unlock it as the *#307# (one website says *#301#) doesn't work - I get the message "Error performing request, SIM PIN required".
Oh hell! Sounds like you have a SIM lock on that sim. Call your provider and see if htey can give you the unlock code. I did that once and t-Mo gave me a code that allowed me to unlock the SIM. But they called it something else.
