Amazon, Unlocked Mobiles and Clove don't seem to be receiving stock until later this month; but, if it's an unlocked Xperia X Compact you're after, look no further than Carphone Warehouse, which will sell you one right now for £360 (almost £20 cheaper than anywhere else).

Apart from Apple's return to the 4-inch form factor with the iPhone SE, Sony remains one of the only companies making decent smaller-screened devices. They aren't severely downgraded models taking advantage of flagship branding either, though unlike last year's Xperia Z5 Compact, the Xperia X this new, smaller model is based on was a mid-range device to begin with.

Still, you're looking at a hexa-core Snapdragon 650 chip, 3GB of RAM and 32GB of expandable storage tucked away behind that 4.6-inch, 720p display. You also get the same 23-megapixel camera with laser autofocus that Sony has equipped the flagship Xperia XZ with. In short, it's definitely worth considering if you're into smaller screens.
