(Telecompaper) Microsoft has unveiled Windows Phone 8 Update that includes a bigger Start screen for more Live Tiles, a new customisable driving mode and better accessibility options. The update will be rolling out in the upcoming months. The bigger Start screen allows users to pin more people, info and apps they are interested in and built-in apps will be scaled to better utilise additional space on 6-inch screens. In addition to larger screens, Update 3 will also provide support for the Qualcomm Snapdragon 800 quad-core processor.
