These are theoretical limits/caps in the current gen technology (and yet I believe some carriers have been testing beyond these here and there for eventual release- of course your hardware has to support it to be useful), highly unlikely to be achieved once much less all the time on either device. And as others have pointed out, Tmo's 3G coverage has been the weakest thus far- in both initial growth, real-world download speeds, and major market coverage. A lot of their cities they cite to pump numbers aren't nearly as big as other cities that are completely void of Tmo 3G. Go figure.

I want my, I want my, I want my LTE.
