From what I can tell, they've said they're for net neutrality on land lines, but not mobile. Mobile internet is another matter, because you can't just add another line to get more bandwidth; bandwidth is limited by physical constraints (e.g., signal-noise ratio, the frequency of the signal etc.). It makes sense for some applications to be "privileged" for mobile. VOIP, for example-- if it had to share bandwidth with enough people downloading a stupid dog trick video on Youtube, it would be unusable. I guess we'll see how it goes.
