We reported earlier this month that Sony has confirmed on one of its forums that the ICS update would hit Xperia S handsets late May/early June, however this is no longer the case.
In its most recent post, Sony now says: "Xperia S will get it (Ice Cream Sandwich) during the latter part of Q2."
ICS already rolling out on Xperia handsets
The post also reaffirms Sony's plans for the Android 4.0 roll out on its other devices, with the Xperia Arc S, Neo V and Xperia Ray already seeing the update and other 2011 Xperia handsets will receive ICS in late May/early June
Sony has put the error down to a mix up: "the rest of the 2011 Xperias will get ICS during late May/early June. Which was the timing I mixed with the Xperia S timing".
However this is going to come as little comfort to Xperia S owners, who have seen proposed April and May dates slip away from them, but hopefully Ice Cream Sandwich will be arriving at the end of June.
We've contacted Sony to find out why the update cycle has taken so long for the Xperia S and we'll update this article once we get a response.
