T-Mobile followed suit on that as well, back when they were itching to merge with AT&T. They even went so far as to brand Samsung's Galaxy S Relay as "4G" even though it was at best dual carrier HSPA+. But the crew in charge of T-Mobile at the time also decided not to bother investing in their network, so back in 2013 T-Mobile US's coverage was absolute shite outside of cities. It just goes to show that marketing weasels and lobbyists, as always, will happily use tech-speak to bamboozle the masses - and the politicians and regulators as well.
