If you’re holding on to the Motorola Electrify M from US Cellular, you should have received the Android 4.1.2 Jelly Bean update from Motorola. Like the RAZR i, this update will bring various new features including Google Now, Face Unlock and Project Butter to the Electrify M.
However, if you have yet to receive the OTA update notification, you can go to Settings > About phone > System software updates to manually check for the Jelly Bean update as well. For more information on the update, you can visit US Cellular support page as well.
