Hello Everyone, A few days ago i bought an iphone 4s from ebay. Everything is fine, but it's locked to att carrier. I checked the IMEI it's clean and out of contract. I request to the seller to unlock it for me, because it's free for her, but she is not interested to do that. She is telling me to call att and give them the imei number, then they will unlock it for me? But i called at +1-800-331-0500 from skype, they are asking for owner of the account's last 4 digit of the SSN number? But i don't have ssn and i don't have any account with att to make a device unlock request, since i am not a US citizen. I live in Banlgadesh. There is other way to unlock this, but it's require an former or current good standing att account, to request a device unlock? But i don't have any friend who are using att servie?? Is there any other way to unlock it through att by call or chat, i have the owner's phone number if it need?? Please someone help me!!! I'll appreciate your help??? Thanks.
