When they did the smart card swap last year I didn't have my 3100 hooked up, so I never activated the card. So today I rushed home to get TV working in the bedroom to prepare for my wife's return from the hospital and I could not find the card anywhere, after ripping the house apart for an hour I had to come back over to spend the night with my wife. I just got to thinking maybe I put the card in the 3100 but I'm not sure. Is there a color difference between the new and old cards? The one in my receiver now is blue. I wish I had have taken down the number but I was in a rush.
