There is no one unlock code. Each individual device has it's own particular unlock code. Unfortunatly, nobody here can provide you with the code. Cingular can unlock it for free (you might have your sister look into that for you) or you need to purchase an unlock code from an 3rd party unlocking service. GSM PhoneSource - When Only The Best Will Do does a good job.
