As far as I know, (I work at us cell) your blackberry isn't going to work anywhere but on a CDMA network to begin with, (sprint) and even then you would need an unlock code to program the phone, so you're probably just SOL unless you decide to go with us cellular...

Does any one know if us cellular blackberry 8630 will work with t mobile or sprint i tried to unlock it but in advanced options when i go to sim card and type mepd it says network disabled does it mean it will not work with other carriers or it is already unlocked?/ pls help me
