Honestly I can actually see this being the reasoning for the existance of the phone app & having certain features on it.maybe a side of "you would need wi-fi to use those services, and we wouldnt' want to make you pay"
Still not quite see the reason to make them *exclusive* to the phone one.
I'm still sticking with my believe that it's another of their weird attempts at protecting kids, forcing parental control & encouraging socialization (aka, go to the shops with the phone for event codes for example, rather than receive at home via wifi), something that's been a recurring trend lately.
