Sony Xperia S available beginning of March, already on preorder
You can actually preorder now for the fairly expected price of around $700 unlocked, which, as these things go, will likely translate to $100 or so bucks lower in the US. Of course, the US has the Sony Xperia ion on AT&T's LTE network to worry about, but it shouldn't be far behind.
Just a refresher - both phones have HD screens and dual-core chipsets - all firsts for the company, along with the strictly Sony logo, again a novelty for its handsets, after the break-up with Ericsson. Unfortunately, the Xperia S ships with Gingerbread, which should turn into Android ICS in Q2 of this year. We made a bunch of camera and video samples with the unit we handled at CES, to aid your decision.
