Sony has announced that it plans to launch the Android 4.0 Ice Cream Sandwich upgrades for the Xperia arc S, Xperia neo V, and Xperia ray in the middle of April. The roll-out will be gradual and is expected to take four to six weeks to complete. Sony says the upgrade will require users to use their PC or Mac to install it, and it will not be made available over-the-air. Owners of the Xperia arc, Xperia PLAY, Xperia neo, Xperia mini, Xperia mini pro, Xperia pro, Xperia active, and Sony Ericsson Live with Walkman can expect to see their upgrades arrive at the end of May or early June.
