Why should people be responsible for knowing the difference between Sprint's 4G network and AT&T's 4G network? The speeds are actually vastly different. This problem existed back in the days when monitor manufacturers liked to "round up" the diagonal length of the monitors and put the actual viewing size in fine print. Some manufacturers would add 3 inches to the actual size of the monitor, just so that they'd "beat out" the competition.
