It looks like we will get some further news on the Android Jelly Bean schedule for Sony Xperia devices in a few weeks’ time. Sony Mobile confirmed via one of its twitter channels that “more detailed timings and info on this (will be provided) by mid-December”.
Sony Mobile has only confirmed timings for the recently launched Xperia T/TX and V, which are expected to get the Jelly Bean update by the middle of Q1 2013 i.e. next February. Therefore, we expect more news on the other 2012 Xperia handsets such as the Xperia S and Xperia P in a few weeks’ time. Remember, 2011 Xperia handsets will not be updated to Jelly Bean and we don’t expect a reversal on this decision.
