Well I have a Cingular sim card, so I could just give them the number on the card and on the phone, then when its unlocked it will work.
I told T-Mobile I will be using it over seas, as ive been told that they will not unlock it for other US carriers. But I tried to get it unlocked once before but the unlock code didnt work so they refiled a report for it. But if it errors again I just want to be sure they wont be able to see its linked to a Cingular account already.
