I am wondering this because every so often someone offers to sell me a receiver and some still come with the blue cards (they might have not been activated for a while or something). Will there be a problem with activating those? Someone called me and I asked what kind of receiver he had and he said he didn't know then I asked him to give me the model number. He told me 2700 so I figured it might have the older card and I didnt want to buy something I couldnt get activated. I asked if he had a yellow card or blue card and he got mad and said that I fix cards and hung up. I don't fix cards but don't want people hanging up on me or getting the wrong idea.
