Error Code 67; No Data Plan! (Again...)

[finality]

Hi, everyone. I made a post about this a little while ago, but the problem is coming back. I'm with Sprint, and I don't have data for my Touch Pro 2. The error code 67 message would pop up constantly, and somebody I suggested I got to Settings > All Settings > Connections > Connections > Manage Existing Connections and delete the one labeled "Sprint #777." It worked, but only temporarily. The connection just keeps coming back by itself no matter how many times I delete it (AND every time I restart the phone, too)! Somebody please help me get rid of this stupid thing for good!

Thanks in advance to all who reply! ((:
