Windows Phone 8.1 might be unveiled to the public only in April at the Build developer event, but some enterprising developers have already been able to get a preview of the SDK, as reported earlier by TheVerge. We had expected more information to pop up once it became available, and thanks to a redditor, who claims to be a high-profile WP app developer(there is proof), some details of the next big update to Microsoft’s mobile platform have leaked. While most of the details are developer-oriented, some of the long standing consumer complaints seem to have been resolved, like the support for installation of apps on the SD card, VPN support and the start of universal apps for Windows Store and Windows Phone Store.
