之前 Sony 亦曾介紹旗下手機升級 Android 4.0 Ice Cream Sandwich 的計劃，當時亦指 Arc S, Neo V 和 Ray 會首先獲得升級。而昨天 Sony 在官網 Product Blog 內清楚寫明是四月中開始！
The first Xperia models to receive the upgrade will be Xperia arc S, Xperia neo V and Xperia ray. For these first models, the rollout will start mid-April and continue over 4-6 weeks.
第二批五月尾開始
隨後就會輪到 Xperia Arc, Xperia Play, Xperia Neo, Xperia Mini, Xperia Mini Pro, Xperia Pro, Xperia Active 和 Sony Ericsson Live with Walkman 升級，開始時間會在五月尾或六月初。
Following on, Xperia arc, Xperia PLAY, Xperia neo, Xperia mini, Xperia mini pro, Xperia pro, Xperia active and Sony Ericsson Live with Walkman will receive their scoop starting from the end of May/early June.
不會有 OTA
今次升級只可透過 PC Companion 或 Bridge for Mac 進行，並不會透過 OTA 推送，用家亦不會接收到通知。
Therefore, we’ll only be making it available for download via PC Companion and Bridge for Mac (i.e. not over the air via 3G or WiFi), and you also won’t receive any update requests or notifications.
另外，Xperia S 將會在第二季的後半段時間升級至 Android 4.0。
Finally, with regards to our all new Sony Xperia S, which will be upgraded to Android 4.0 starting from the later part of the second quarter, we will get back with more detailed information on timing over the next weeks.
