Unlocking the radio might allow us to roam on AT&T's LTE when its up. AFAIK, VZW and AT&T LTE will use the same frequency.

Not true. ATT will be using the lower end of the 700mhz (704-745) and VZW is in the higher 700mhz (746-787) range.

Metropcs is in the 1700 range so that's way out of the question to. Guess the didn't consider in-building penetration lol.
