My apologies in advance if this has already been discussed. I tried searching for it. I puchased my shift about 2 months ago in Las Vegas (Pacific Time zone), I moved to Oklahoma City, OK 2 weeks ago (Central Time Zone). My phone initially changed to Central time automatically but it reverts back to Pacific time. It continues to revert back to pacific time when I manually set the time and time zone & when I have the phone automattically "use network-provided values"...Is there any other ways to set time other than menu - settings - set date and time?
