We've been twiddling our thumbs waiting patiently for the littlest of Sony's new-look smartphone lineup, the Xperia U, to arrive in earnest. It's a bit of a relief then to see the Android 2.3 phone go on sale at Three UK. You'll be getting what we saw back in Barcelona, including Sony's Timescape interface and the trick color light-up strip. We're guessing that most will see the cheap-as-chips price as the real selling point: the Xperia U costs £170 ($269) without a plan, and it's free as in beer on a two-year contract for £23 ($36) per month. O2, Orange and T-Mobile will expand UK carrier choices soon, but if you're looking for a fresh entry point into Android, Three can take care of you today.
