If small is beautiful when it comes to mobile phones, the Sony's Ericsson X10 Mini will certainly turn a few heads on the shelves of the Carphone Warehouse.The mobile is now available via the phone retailer, which has deals for all the major networks on contract, as well as a pay-as-you-go deal if you want to drop a hefty amount of cash upfront.At just 16mm wide and weighing only 88g, it's being pitched as the travel-sized Android, the size of a credit card more or less. Running Android 1.6 (unless an upgrade has sneaked in of late), the mini X10 has a 600MHz Qualcomm MSM7227 processor, 3G and Wi-Fi connectivity, Sony Ericsson's Timescape interface to keep all your networking organised and a 2.5-inch QVGA touchscreen display. There's also GPS, a 5-megapixel camera with autofocus, a Walkman media player and three interchangeable back covers - black, pink and silver.That £15 deal is via the Vodafone network, but you'll have to sign on the line for two years to get it. Other prices vary, but if you want it on a pay-as-you-go, expect to pay £199.95. All the deals can be checked over at the Carphone Warehouse website or instore right now.
