Unveiled on 31 August 2011 at Sony's press conference in conjunction with IFA in Berlin, Germany[3][4] and scheduled for release in October,[4][5] it was released in October 2011. The device's primary improvements over its predecessor are a 1.4 GHz Scorpion SnapdragonCPU and 14.4 Mbit/s HSDPA, compared to the same model at 1.0 GHz and 7.2 Mbit/s HSDPA in the Arc. Aside from the CPU speed upgrade and HSDPA speed upgrade, additional hardware remains unchanged.[6]
The Xperia arc S, along the Xperia Mini Pro, would not be receiving an Android 4.1 Jelly Bean update,[7] as Sony Mobile Communications officially confirmed via their Facebook page on 26 July 2012. However, this statement was then retracted and Sony has issued a new statement stating they are investigating the possibility of software upgrades for the two devices. However, as of December 2015, the upgrade has not materialised.
