The Sony Ericsson Xperia X10 mini has gone on sale in the United Kingdom.
Little bigger than a credit card, the Xperia X10 is the world's smallmost compact Android-based smartphone, weighing in at just 88 grams.
In spite of its diminutive size, the smartphone boasts a 2.55in capacitive touchscreen, Wi-Fi, GPS and A-GPS, a 5MP camera and LED flash, along with modified versions of Timescape and Mediascape, integrated social networking services and a number of exclusive apps.
The phone is available for free on a £15 per month contract for two years with Carphone Warehouse in Ireland. For those who want to buy the phone for use on Pay As You Go, the handset will cost around £199.95.
Xperia is available with a choice of three coloured backs: black, pink and silver. The Xperia X10 is available in the UK from 3, O2, Vodafone and Carphone Warehouse. Users can download mobile apps from Sony Ericsson's PlayNow portal and Google's Android Market.
