Looking at the sim-free retailers, Clove has discontinued notices on its listing for both the Xperia arc and Xperia neo. This isn’t so much of an issue for the Xperia arc S, after all its identical to the arc (including price) and comes with a 1.4GHz processor instead of 1GHz on the original.
However, this is more problematic for those wanting the Xperia neo, arguably the best all-rounder of the 2011 Xperia range, both in terms of price and functionality. Most places only stock the Xperia neo V which comes with a weaker 5MP camera, as opposed to the neo which had a 8MP Exmor R camera sensor. We don’t know whether this situation is being repeated in other regions around the world, however we wouldn’t be surprised.
Let us know in the comments below if the Xperia arc and Xperia neo is still on sale in your part of the world. Our guess is that they’re probably being phased out.
