Good news for Sony fans: the company is finally starting to roll out Jelly Bean updates to some of its more notable 2012 smartphones. The former headliner Xperia S, its brother the SL, and the camera-focused SL all have Android 4.1 waiting for them. Users will need the a Windows PC and the Sony PC Companion to download and install the updated software, which includes a refreshed kernel as well. Xperia Blog got some screenshots of the 6.2.B.0.200 firmware being flashed to a French Xperia S.
I suppose you have to give Sony credit for at least keeping its customers informed. Today, the manufacturer announced an update to its plans for bringing its phones up to Jelly Bean. If you're rocking the Xperia T, Xperia TX, or Xperia V, you should see Android 4.1 "during February and March." Of course, this will depend on what market you're in or which variant you own.
Following those flagships, the Xperia P, Xperia J and Xperia go will start to receive their upgrades starting around the end of March. Following that release, the Xperia S, Xperia SL, Xperia ion and the Xperia acro S will be updated "in the subsequent weeks." Of course, schedules are always subject to change, but all of this information lines up pretty well with what we've heard before from the company.
