At Mobile World Congress 2012, we learned that we can expect to see the three members of the Sony NXT family of Xperia Android smartphones, the Xperia S, Xperia P, and Xperia U, made available unlocked for purchase at Sony stores and online in the U.S. in the June/July time frame. The Sony Mobile executive we spoke with also hinted that we could well see the phones available from a big box retailer or two later this year, though no particular chains were mentioned. Sony did say that it was going to be “aggressive” with distribution of the new devices, and that it is working towards carrier deals.source: Sony Mobile
