I just saw the note about LTE being turned on early in Kansas City, so I tried to change my S3 to test it out on Sprint. So, I did Settings | Wireless & networks -- more settings | Mobile Networks | Network mode and chose LTE/CDMA instead of just CDMA. It says it has to reboot and then it comes right back up in CDMA only mode again. Is there something else I should be doing?
Come on LTE in So Calif
