Originally Microsoft released the Windows Phone 8.1 update in the middle of April, and even though it was a build aim for developers to test, anyone willing to void the carrier’s warranty and setting up a developer account was able to download and install the update. The new update is available immediately and users can simply go to Settings, Phone Update, and check for updates to download the new bits. Once the operating system gets updated the version will jump from 8.10.12359.845 to 8.10.12382.878.

This is just an update to fix things before the software releases to the public. For those still wondering, Windows Phone 8.1 includes an array of changes, improvements, and features including Cortana, Microsoft’s personal digital assistant — limited to U.S. for now –, new Start screen background personalization, highly requested Notification center, Word Flow keyboard, and many more features.
