After updating to 6.1 my iPhone 5 no longer auto switches when in an LTE area. In order to be on LTE I have to go into the cellular settings, switch off LTE and then after a 10 second wait or so, I switch back on LTE and it connects to LTE in a split second. I'm thinking the 6.1 update screwed something up. I have rebooted several times and it doesn't fix the issue. What a pain in the ass this will be just to use LTE. Prior to the update it switched beautifully between 3G and LTE. Anyone else having this issue in Kansas City or other Sprint LTE cities?
