http://tech2.in.com/news/smartphones...-mayend/307512Sony’s Xperia S may have been a hit, owing to its great camera, but the fact that it’s still running Gingerbread has been a bit of a turn off for many. Worry not though, as Sony plans on rolling out the ICS update towards the end of May or early June. Users in India will be getting the update around this time as well, although it’s not entirely certain if everyone will at the same time, due to the phase-wise roll-out. Sony announced this through a support forum, "Xperia S is planned to get ICS somewhere around late May/early June. That's what's been said and that's still what we're sticking to. Any other dates (such as "June/July") is just speculation," They also added, “The roll out is, as always, gradual and will not happen overnight for all phones. Some phones might get the update in late May whilst other will get in mid-June.” If you don’t get it by May end, then chances are that you’ll get it in the first week of June, but whatever happens, Sony will update all their Xperia S handsets to ICS by mid-June.
About time, it should have been launched with ICS !
