将于10月15日首发的小米3看来是性价比较高的一款新手机，具体参数见：
http://www.xiaomi.com/mi3。
但是网上有老美说，,t-mobile uses two bands for 3g those band are 1700 and 2100MHZ, the Xiaomi Mi2, Mi2S and the upcoming Mi3 have the bands 850MHZ, 1900MHz and 2100MHz open for 3G connections, so these devices are lacking the 1700MHZ 3G Band to be able to connect to T-mobiles 3G network.
具体有没有谁用过小米加T-Mobile的卡？
谢谢！
