T’is the season to be leaky. Not only did an iPhone prototype recently find its way on to the internet, Engadget just published leaked information on the Dell Lightning – a yet-to-be-announced Windows Phone 7 handset. According to the leaked spec sheets the Dell Lightning boasts a 4.1-inch OLED touchscreen, a 5-megapixel camera, HSDPA, Wi-Fi, GPS, a slide-out Qwerty keypad and a 1GHz Sbapdragon processor. In other words the Lightning is a beast. One of the leaked documents states that the Lightning will be available in Europe, which we assume means the UK, on T-Mobile and will be out at the end of the year.
