#1 is most likely, using street view on google maps there is a tower not far from there that looked like it only had 1 provider on it. Is there a tower in Bear Creek too?
Any idea when we will hear more details and whether we'll be happy or not? It would be a great fit, allowing Sprint to focus on metro builds and USCC on rural. Of course t-mobile and ATT could both benefit from same.
If you go to the engineering screens it will show you the band you're on. I'm not sure the dialer code you need, I know they've posted it on the iPhone6 thread somewhere.
