Earlier today, US Cellular had officially announced on their Facebook that they have begin to roll out the OTA Android 4.1 Jelly Bean update for the Samsung Galaxy S3. If you’re a US Cellular customer but has yet to receive the update, fret not, you’re not being missed out as the update will take several days to reach all users.
Nevertheless, you can go to Settings > About phone > System software updates to manually check for the update as well. So have you receive the Jelly Bean update from US Cellular?
