Should the 722 come with a smart card? I ordered one from Dishstore.net and it didn't have one in the box. I thought maybe it was built in like on the 211 I have but I see a slot that looks like it's for it. Whats the deal here? Everything looked sealed except for the wrapper around the manual looked opened. Did I get one missing the smart card or do I use my old one or not need it or what?
