Sony Ericsson was the first OEM to officially announce the Ice Cream Sandwich update for their current line up of smartphones and now they've revealed a roadmap of when to expect the said update.The first smartphones to get the upgrade are Xperia arc S, Xperia neo V and Xperia ray. Soon after, starting from end April/early May, Xperia arc, Xperia PLAY, Xperia neo, Xperia mini and mini pro, Xperia pro, Xperia active as well as Sony Ericsson Live with Walkman™ will get their upgrades.

The updates for each model will be done in phases. This means for any given model it can take up to a month before you get the update from the date it's announced. If you ask me the schedule is quite puzzling. Most of these Xperia phones run the exact same software and the exact same hardware so such parity between for example Xperia Arc and Arc S makes little sense. April/May is a long, long way away for the early adopters of Xperia phones, but I suppose it's a price you have to pay for a flashyproprietaryskin.
