Good news, Sony Ericsson fans! SE has allegedly confirmed that all of its 2011 Xperia Android fleet will get updated to the “next Android platform.” Sony Ericsson Netherlands replied to a question on its Facebook page, and this could well mean Android, 4.0 Ice Cream Sandwich.
leave a little room for doubt as the statement “next Android platform” is pretty vague. The comment in Dutch mentions Android 2.3.4 Gingerbread, so by “next” it’s possible that SE is referring to another iteration of Gingerbread.Now, again, this was published by the official SE Netherlands account, so it sounds pretty official. We would however
roll out in 2012, if true. The 2011 SE Xperia Android lineup include the SE Xperia PLAY, Xperia neo V, Xperia neo, Xperia arc S, Xperia arc, the Xperia mini pro. We've reached out to Sony Ericsson for a comment and will update you on that whenever we get a meaningful confirmation.
