So I did some driving today with the app "RF Signal Tracker" running to create the map below. Two things:
1. There is definitely some live LTE, especially around the Cupertino area. It doesn't allow for a great connection... connects for a few seconds, then back to 3G, but it is definitely there. Seems like a work-in-progress
2. eHRPD seems to be everywhere. You can see there weren't any areas I drove that didn't have it. Is it safe to assume that means work has begun on multiple towers in the South Bay? Not sure if eHRPD automatically means the NV process has started?
Green is LTE, Purple is eHRPD
