Good news to most of the Xperia owners out there! Sony has confirmed today that 3 of its latest flagship, namely the Sony Xperia T , Sony Xperia TX and Sony Xperia V will be receiving the Jelly Bean update by the first quarter of 2013.
Thats not all, slightly older devices like the Xperia S, Xperia Arco S, Xperia Ion, Xperia P, Xperia Go and Xperia J will receive the update right after the devices. If your device is not one of the device mentioned above, chances are that you are holding on to 2011 Xperia models which Sony has confirmed they will not be updating due to certain limitations from those devices.
