SFR, the French telecommunications operator, has published a timetable detailing when software upgrades for Android and Windows Phone handsets are expected to arrive. Interestingly, under the Sony segment, SFR says that the Xperia S Android 4.1.2 Jelly Bean is expected in May 2013.
What we don’t know is whether SFR has any inside track on launch dates or whether it is making forecasts on publicly available information. However, given its status as a carrier, we would expect them to at least have an idea on when to expect it. In the same table, it says that the Xperia go JB update will land during April, whilst the Xperia T update is out now, as we all know already.
