Folders, new resolutions coming to WP 8.1 Update 1

Microsoft has accidentally spilled the beans on Windows Phone 8.1 Update 1, and it's going to be a relatively small update for users, but a big one for OEMs and thus the platform. The number of user-facing features is small (Windows Phone is finally getting folder support!), but it increases support for different resolutions and screen sizes - up to 7". More features might be coming that aren't yet leaked, but the focus of the update is clear: hardware support.
