Just cycled through here and there's a Sprint Keep Site within range with 25+26+41. 25 is still 10x10, while 41 is the same 10 MHz at the top of the band that I saw at the airport on Friday night. Speeds aren't great, but signal isn't bad, so my guess is that they turned up the power on the site vs. where it was before (B26 is -101 RSRP and I know the site nearest me is gone).
Will be downtown for fireworks tonight, so will see how networks perform. I have mmW-enabled VZW and AT&T SIMs to play with.
