There's a wealth of technological wizardry in the Apple iPhone X, but what matters most is that it's so great to use. The Super Retina HD display makes graphics and videos on the 5.8-inch screen come alive, while the huge 256GB storage capacity makes handling even large files a snap. The space grey colour scheme is distinctive, while the processor has the power to deal with the toughest tasks. This device is locked to Three and compatible with Vodafone, EE, O2 Carriers.
