Is there a way to tell if my pin has been released on my old 8100, so I can sell it, because I got a new phone? When I used the 8100 it was only for pre paid, so no email or nothing like that but person that wants to buy phone is asking about released pin and I have no idea how to deal with the situation. I used my old phone number from tmobile pre paid and took it to sprint so I guess that voided my sim, Im not sure anyway any help would be appreciated.
