I have a blackberry 9330 which have had no problems until now. It started shutting down once in the evening. Was able to restart. I took it to a service center about the problem. Idea was to reset to factory defaults. Did so. Before leaving the center contacts were updated. After coming home, when I do backup assistant, it asks for pin. Put in correct number. Keeps asking for a pin. Even tried to change it. Have deleted and reloaded it three times. Still will not sync due to pin. Question is now what?
