Sony Ericsson have now updated their news press page on their website, to include more information about the Xperia Arc S which was announced today. We already learned that the Xperia Arc S would have a 1.4GHz processor compared to the 1GHz processor on the Xperia Arc. We now know that the Xperia Arc S will render web pages 20% faster than the Xperia Arc and the camera start up speed and media conversion will be 25% faster. The Xperia Arc S will be available in Midnight Blue and Misty Silver like the Xperia Arc, as well as Pure White and Gloss Black. The Xperia Arc S will also be available in Sakura Pink. This will most likely be like the Sakura Pink Xperia Arc and only be available in Japan. Other specifications appear to be the same as the Xperia Arc.
