Hi guys! T-mobile just launched 4x4 MIMO in 319 cities. I read some rumors that Att iPhone 7 is going to have Intel modem that doesn't support 4x4 MIMO. All other carriers will have Qualcomm X12 modem with support 256 QAM 4x4 MIMO. Now I have a big question mark what iPhone7+ to buy? Last year I bought Att model due to B30. But this year I may be get a T-mobile model (is it going to support B30? ). Any news and rumors please post here.
