TiVo and DirecTV in a Cellular-Only Household?

Balthisar asks: "Like so many others, my wife and I have recently made the move to pure mobile telephone use, and have disconnected the landline permanently. Today, I turned on the TiVo and received a stern warning that only three days of the program guide remained! I screwed up. Anyone have a good emergency way of refreshing the program guide while I wait for my TiVo networking card to come in? An additional concern is DirecTV: I never use Pay Per View, but it's not connected, either. Any horror stories about not having your DirecTV connected to a phone line? If you don't have any advice, at least take this as a cautionary tale to make a good checklist before taking the leap of eliminating your terrestrial line!"
