Ok, I just purchased a 9530 from a guy who had it unlocked and he was using it with T-Mobile service. I am with Cincinnati Bell, and when I place my SIM card it tells me it is an invalid SIM... What do I do? I currently have a Pearl through CBW that works fine, so it isn't the SIM card. What can I do to make the 9530 like my SIM card? lol
