According to a new report, Microsoft is expected to roll out the Windows Phone 8.1 Preview for Developers Program on April 10th. This preview program allows developers to install the operating system before its general availability.
Microsoft is rumored to be releasing Windows Phone 8.1 on April 10th for developers as part of this program. If you are not familiar with the Preview for Developers Program, all you need is an app from the Windows Phone Store and a free App Studio account. This will allow you to install any updates before the update is made available to the general public.
Unless plans change last minute (which they tend to sometimes), everyone who opts into the Preview Program can have Windows Phone 8.1 on their devices. When the update does go live for the general public, you can update to the latest version of the operating system and firmware.
Microsoft's Build 2014 Developer Conference is set for April 2nd, and it appears highly unlikely that we will see Windows Phone 8.1 released during the event. More on this as it develops.
