Microsoft Windows Phone 8.1

Microsoft is already working on the next build for its Windows Phone 8.1
operating system, according to the benchmarking site - WPBench. The
 data from the yardstick shows us a new build number 8.10.14130 for
 Windows Phone 8.1 while the current OS build for the GDR3 version
 of WP 8.1 is 8.10.10532 and for the developer preview version of
Windows Phone 8.1 is 8.10.12397.

The results from the WPBench reveal that a developer has been testing the
 8.10.14130 build for the past five days. If the rumors are to be trusted,
 the update is scheduled to roll out as early as next month and the new
firmware will come out with the inclusion of native folders along with the
 ability to double the height of the live tiles. For now, the update will be
 available for all the registered Microsoft Windows Phone.
