I installed this update and most everything works great. However, although I live in an area with 4g, the phone will periodically shift to 3G. It only happens every few days or so. When I reboot the phone, it goes back to 4G. Not sure whether or not anyone else has noticed this. BTW, when you first install this software, it defaults to global. You have to reset it to lite/CDMA mode. Regards.
