Today, Sony has officially confirmed that it will start the delivery of Android 4.0 Ice Cream Sandwich for its Xperia series only in mid-April.
The roll-out was initially expected to start sooner than that, but the company
won’t have the OS upgrade available for users for the next two weeks, it seems.
In mid-April, owners of Xperia arc S, Xperia neo V and Xperia ray will start receiving the update, the company announced. The deployment will continue over 4-6 weeks.
In May/early June, the company will start to roll out this upgrade to other handsets in the series, including Xperia arc, Xperia PLAY, Xperia neo, Xperia mini, Xperia mini pro, Xperia pro, Xperia active and Sony Ericsson Live with Walkman.
Apparently, the update to Android 4.0 won’t arrive on Xperia S until the late part of the second quarter, a post on XperiaBlog
