Hello everyone. Im new here and my friend just jailbroke my 2g Iphone with black rain and snow didnt show up so i looked things up and heard of bootneuter. i ran that and watched videos on it and still, it wont unlock the phone. I want to unlock it for my sister so she can use her AT&T GO SIM. Is this possible? Every time i put the sim in after rebooting, it still says no service and now im really frustrated. any help would be MUCH appreciated. Thanks.
