I think the newer Leafs got a free replacement modem, older ones had to pay. Ford provided free replacement 3G modems for the Focus Electric and the two Energi PHEV models. Kind of surprised me. So my "MyFord Mobile" finally started working for me at the end of November after I got the new modem. We have AT&T 3G, never did have 2G here because the tower was installed after the announced 2G shutdown back in August 2012.
Of course, Ford's software still sucks.
