^4G is available in Naples, FL now! Make sure you turn on your
   4G antenna. On the HTC EVO 4G, you go to: Settings then Wireless
   and Networks then 4G Settings. Click 4G Antenna. It should scan
   for the new 4G tower and connect. (I don't have an HTC EVO 4G
   but I figure this wlil help those that do!). Good job sprint.^
