I just saw on another (non-technical) forum a guy said he stopped paying on his Cricket phone and his voice service stopped in early January. He claims his 3G data connection still works. At first i thought he was confused between wifi and 3G but he says he can move around town and he doesn't have to find new wifi hotspots.
It might just be a case that they haven't shut down his data connection yet.
