Hi, I have placed an order for the unlocked M8 from the HTC website in the US. From what I have read it supports AT&Ts LTE band. But, I want to be sure before they ship it to me. Has anyone activated the developer or unlocked version on ATT and been able to use LTE? Was There anything special ATT needed to do? Were they willing to do it or give you any problems? I'm currently on Verizon but I need to port my number since Verizon coverage is horrible where I work, they have installed ATT repeaters in the building and others get great service. Thanks.
