Well, in a way that's some sort of good news, but shouldn't they actually work in LTE instead? Playing this catch up game will not really help them grow the business. Except maybe if they are looking at a different market segment.

HSPA+ is actually quite fast though; in my experience it's comparable to WiFi.

T-Mobile is supposed to absorb MetroPCS's LTE network, IIRC.

That's not exactly a sterling asset.
