I live in Napa, CA and for the past 3 days I've had intermittent 4G coverage. We don't have 4G here yet in Napa, but my Droid Razr Maxx showed that I did for about 20-30 minutes in the mornings of the past few days. I'm just wondering if that's an indication that they might be testing it in my area, or just a weird occurrence (?). Has anyone else had this happen? Is anyone else here from the Napa/northern bay area?
