AT&T Lumia 520 and 925 owners can now update to Windows Phone 8.1

Microsoft first showed its latest major update for Windows Phone earlier this year. After an open developer beta which lasted for a couple of months the company finally started rolling out the update a couple of weeks ago. Folks with carrier devices had to wait a bit longer to receive the update and today the wait ends for AT&T Lumia 520 and Lumia 925 owners. The carrier has finally released Windows Phone 8.1 update for both smartphones. Windows Phone 8.1 is one of the biggest update that Microsoft has made for its mobile platform. It is compatible with any device that’s running Windows Phone 8.0. AT&T has previously rolled out the same update for the Lumia 1520, one of the high-end models in the Lumia family.

Months after its unveiling in early-April at Build 2014, Windows Phone 8.1 is finally rolling out to compatible smartphones. Among the latest Windows Phone 8 devices to receive the coveted software upgrade are the AT&T variants of Nokia Lumia 925 and Lumia 520, the latter of which being a branded version of the most popular Windows Phone to date. AT&T customers using Lumia 925 and Lumia 520 can apply the software upgrade right away,suggests the US mobile operator, by heading to the Settings menu, opening the phone updatesubmenu and tapping on the check for updates button, the last of which will reveal the option to kick off the install. Windows Phone 8.1 is delivered to AT&T customers with Lumia 925 or Lumia 520 through the Nokia Lumia Cyan firmware upgrade, which also introduces some optimizations and apps specifically designed for Nokia-branded devices. You can check this story I wrote about the firmware for more information on the changes.

According to a support page on Nokia’s site, the Lumia Cyan firmware upgrade is only available for the AT&T version of Lumia 1520, but not Lumia 925 or Lumia 520. Lumia 1520 is, apparently, the only Nokia-branded device in US to have received it, per said page. Its software version number is 02061.00074.14273.33019.
