I got a trafone from one of my friends and the service was expired, so I can't use it until I get another card. Well I was screwin around with it and went into the code entry mode, and then hit exit and it said service disabled. So now on the desktop, or whatever you call it, it says Service Disabled in place of the due date for a new card that it had previously displayed. What's the deal? It's it still working and I will be able to add a card to it?

Thanks
