No idea why it has taken Sony Ericsson so long to bring their Xperia X10 to the American market. Nevertheless, from what we hear, AT&T should be bringing the Sony Ericsson X10 to the United States sometime between the mid of August and mid of September. Spec-wise, it looks kind of old at the moment. The device features an Android 1.6 device and at $345 is no bargain for consumers to pick this one over other devices with much more modern specs. We had earlier reported that the device could launch in Q2 of 2010.
Now, there is no word on how much subsidy AT&T is planning to offer on this phone. Considering that this is phone has pretty mundane specifications and the fact that it has existed in other parts of the world for some time now, expect some heavy subsidy as Ma Bell gears to sell the stocks out as quick as possible.
Nevertheless, hold on for some official communication from AT&T before throwing in your money at an alternative.
