T-Mobile announced its network modernization plans, which include refarming some of its 2G 1900MHz spectrum to be used for HSPA+ and an LTE deployment
Three things wrong with that statement. First thing is that there is no mention of rural EDGE areas. Second is that 2G has been on 1900 for ages in all areas. They don't specifically mention where. When they say modernization, they could have meant cities, which is exactly what is happening right now. And the very convoluted article that you seem to take as TMo gospel also sort of says that LTE is on PCS, which is wrong because its being deployed on AWS.
Yet again you fail to find any concrete evidence. Well done. I hope your BS continues.
