AT&T has an LTE network running right now in Chicago, San Antonio, Dallas, Atlanta, Houston but only for internal testing. Its supposed to go live in August and the first device will be a USB modem.
The interesting part is that they plan to use 700mhz (like Verizon) and 1700/2100 AWS just like Metro does currently
This means that potentially an AT&T phone could LTE roam onto Verizon and Metro OR a Metro phone could roam onto AT&T
Now the question is, will they enable such a thing?
