What's the difference with tethering to save a step? It's the same data over the same network, but only one method is acceptable?
Difference being it is their network. If they so dont do it or we will cancel then you dont do it.
Thing is most carriers dont really care about the occasional tither or wifi hotspot.
Its the people that bought the phone just to tether. Why pay 60 bucks a month for internet to check facebook and surf porn when you can pay 25 and do the same thing?
