Sony is releasing the Jelly Bean 4.1.2 firmware update for the Sony Xperia SL, Xperia acro S and expanding the availability of the Xperia S update, which reportedly started received it a week ago. We guess the rollout needs time to reach everybody with the current firmware currently making the rounds in France.
The said 4.1.2 update for the three Xperias was certified at the beginning of the month and it didn't take that long to actually be released.
The Sony Xperia ion is next in line to receive the update - fingers crossed.
The phone will notify you when the firmware is available or you can check it through the Sony PC suite.
