Has anyone visited »network.sprint.com as Sprint has been working on their 3G network heavily in all areas! Just in my area Fort Lauderdale/Miami Sprint has and will be making over 700+ tower upgrades! On that site you can also see the location of all of Sprints towers. This site has nothing to do with the Network Vision though so you won't find an LTE information. Everything on that site is strictly normal 3G improvements.
