I had my iPhone hacked with ver 2.1 (i'm not 100% sure about the ver #).
I've click the update to ver 3 in the Itunes and then got a message my sim is not supported. I then tried to restore the iphone but it had failed.

Now, in Itunes I get a message that my sim is no supported and on the phone I see the restore image and get a message I can only make emergency calls.

Could anyone help?
