New firmware (4.1.A.0.562) was certified by the PTCRB for four 2011 Sony Xperia handsets – the Xperia arc, Xperia arc S, Xperia neo V and Xperia ray. Whilst it is difficult to know exactly what this firmware represents, the likelihood is that this will be the Android 4.0 ICS Xperia update. So why do we think this is ICS?
Well the beta ICS firmware versions for the Xperia arc S and Xperia PLAY were both prefixed 4.1.X.X.X. Also Sony Mobile has confirmed that the first 2011 Xperia handsets to get the Android 4.0 update will be the Xperia arc S, neo V and ray. The only thing spoiling this theory is that the original Xperia arc has also been certified with the same firmware and SM recently confirmed a late May launch for the arc. Either way, this still looks like ICS firmware to us, which means the countdown to Android 4.0 for Xperia users has begun.
