I have an unlocked iPhone 5, model A1428. Apple says it supports LTE bands 2, 4, 5, and 17: https://www.apple.com/iphone/LTE/ I saw that Tmo has a new coverage map and that there's growing 1900 MHz LTE coverage in previously EDGE only routes. It's probably going to be enough coverage that I could leave AT&T for Tmo. I though my iPhone 5 would support the 1900 MHz Tmo LTE, since Band 2 is 1900 MHz, but the people on Howard Forums say that Tmo's 1900 MHz is actually Band 25: http://www.howardforums.com/showthread.php?t=1855857 Tmo's website says the CDMA iPhone 5 w' Band 25 works on their 1900 MHz LTE. It doesn't have Band 4(AWS) though so it doesn't work on most of their 1700/2100 LTE. Is Tmo's 1900 MHz really only Band 25? Anyone know if there's any possibility my iPhone 5 works on 1900 MHz Tmo? I can buy a new phone if necessary but I'd rather keep my existing phone if possible.
