Microsoft will begin officially rolling out Windows Phone 8.1 on June 24th. This should coincide with the launch of the Lumia 930, Nokia's upcoming flagship.
Just like other iterations of Windows Phone software, 8.1 will feature the typical 3 years of software support and updates.
Microsoft will make updates available for the Operating System, including security updates, for a minimum of 36 months after the lifecycle start date. These updates will be incremental, with each update built on the update that preceded it. Customers need to install each update in order to remain supported. The distribution of these incremental updates may be controlled by the mobile operator or the phone manufacturer from which you purchased your phone, and installation will require that your phone have any prior updates. Update availability will also vary by country, region, and hardware capabilities.
Windows Phone 8.1 brings a host of new features and seems primed to make Microsoft's mobile OS a much more intriguing option for consumers.
Why does the US 520 phone I just purchased still say 8.0 on 7/2/14
It's 26th, still nothing here... :-(
