hi, I just a got a new X201 tablet, i'm trying to install a Gobi 2000 WWAN card, 2 question 1) do i have to get it from Lenovo's site? will a ebay gobi from HP work? 2) the only reason i getting this card is b/c the GPS feature, i don't need others (ie 3G), do I have to pay subscription for the GPS ...
