Sony 在旗下的 developer 網頁，發佈了適用於 Xperia Arc S, Xperia Neo V 和 Xperia Ray 的 Android 4.0 Ice Cream Sandwich Beta ROM。
Today we release an Ice Cream Sandwich (ICS) beta ROM, as a follow up to the previously released ICS alpha ROM. In line with our goal to support the open developer community, we want to give you the chance to try out our coming upgrade to ICS (Android™ 4.0) in this beta version.
相對於 Alpha Release，這個 Beta 版本亦有多項改進。
– 用戶界面改進
– 鎖屏畫面可開啟相機和操控音樂播放器
– 改善 GSM, FM Radio Firmware
– 電郵界面改進
– 快速撥號
不過由於是 Beta ROM，內裏不會有 Google Apps, Bluetooth, Wifi
Please note that the Google Mobile Services (GMS) apps (for example Gmail, Google Maps and Face Unlock), Bluetooth™ and Wi-Fi™ are not included in the beta release due to that they are still waiting for the certification and type approval to be finalised.
若果你有刷 ROM 經驗，可下載自行刷 ROM！要留意只適用於版本為 4.0.2.A.0.42 的 Xperia Arc S, Xperia Neo V, Xperia Ray，並需要先行 Unlock Bootloader。
若果你是日常用家，還是等待 Sony 的官方正式版本發佈。可以先欣賞在 Xperia 手機上的 Ice Cream Sandwich 操作示範。
