The Android smartphone is the first to feature an Intel chip as the computer processing giant attempts to invade ARM’s territory.
The handset, available for £200 on pay as you go, boasts high-definition video on its four-inch screen and an eight mega-pixel camera.
Vodafone also unveiled a new smartphone yesterday, aimed at the other end of the market.
Dubbed the Smart II, the £70 phone features a touchscreen display, high-speed 3G and wifi connectivity, GPS and a 3.2 megapixel camera.
Vodafone said the Smart II will “introduce non smartphone consumers to a new world of content and services”.
