Sony has treated us to the surprise unveiling of the world’s slimmest 5.3in smartphone

Somewhat out of the blue, Sony has announced a new smartphone in the form of the Xperia T3. Smartphone makers like to make big claims with their devices and Sony says that the new 7mm Xperia T3 is the world’s slimmest 5.3in smartphone. And we wouldn’t want to rain on its parade by suggesting it doesn’t have a lot of competition in the 5.3in-screen smartphone category.
