Just FYI, I'm not attacking you with this. I see accusations always slung around about how terrible T-Mobiles network is, or that, in general, T-Mobile is less expensive because they don't have the same coverage, reliability, or signal penetration. To an extent, I'm sure that's true. That said, if AT&T and Verizon were not feeling threatened by either T-Mobiles pricing, network, and/or extras I don't think they'd be reacting nearly, as much.
Dropping prices and eliminating subsidies isn't a token response to some who is just supposedly blowing a lot of hot air. So it's always strange to me when I see others dismissing T-mo.
