4G is available in Naples FL! Here's how to activate it:

   ''To verify if it is a network authentication issue, try this.
   First, go outside or in a car. Go to Settings > Wireless &
   Netowrks > 4G Settings. Then click to turn on 4G Antenna. After
   it's turned on, click ''Tap to Scan for 4G Service.'' Under the
   4G box it should say ''Scanning...''If it stays scanning and
   then just goes to Disconnected after awhile, then it is not
   getting a signal from the tower. The tower may be out of
   service.If it changes to ''Connecting to Sprint...'', then it is
   seeing the tower.If all is working well it will changes to
   ''Obtaining IP Address...'' to ''Connected to Sprint.'' If you
   are having the same authentication issue that we have here in
   Albuquerque, then it will say ''Connecting to Sprint...'' but
   never go on to obtaining an IP address. It will just get
   driopped after a few seconds and go back to Scanning. Then
   repeat it over a few times never connecting. Then it will go
   back to Disconnected. When you get a chance, give this a try and
   let me know what it does. I have a master complaint I am working
   on with Sprint that includes these towers that will not
   authenticate. It's currently affecting about 10% of the
   Protection Sites. Thanks!'' via a sprint community post.
