Sony Mobile 在官方 Blog 发布消息，Xperia S 将会在六月尾升级至 Android 4.0 Ice Cream Sandwich，紧随其后是 Xperia P，而 Xperia U 就会在第三季升级。
而其他 2011 Xperia 手机，Xperia arc, Xperia neo, Xperia mini, Xperia mini pro, Xperia pro, Xperia active 和 Sony Ericsson Live with Walkman 亦会在下星期陆续升级 Android 4.0 Ice Cream Sandwich。
Xperia Play 不会升级
但另一方面，Sony Mobile 明确表示 Xperia Play 不会获得 Android 4.0 Ice Cream Sandwich 升级。Sony 指经过多重的内部测试，发现 Xperia Play 若运行 Android 4.0 会表现得不稳定，尤其是游戏方面。所以 Sony Mobile 决定不为 Xperia Play 提供升级。
In regards to Xperia PLAY, after extensive in house testing with our developer teams and working with our partners, we have concluded that a consistent and stable experience, particularly with gaming, cannot be guaranteed for this smartphone on Ice Cream Sandwich – therefore, we will not make the Android 4.0 upgrade available for Xperia PLAY.
This decision was also verified when we received similar feedback from the developer community; both experienced developers and advanced users, along with game content providers following our ICS beta ROM for unlocked Xperia PLAY smartphones.
