It was two days ago that we finally saw a sign that the Lumia Black firmware update would be out soon for T-Mobile’s Lumia 521. On Nokia’s support website the status of the update went from ‘waiting for approval’ to ‘coming soon’. It still listed as coming soon on Nokia’s support page, but we’re getting a number of tips that Lumia Black has begun its over-the-air rollout for the Lumia 521.
Lumia Black brings a handful of Lumia specific features to the Lumia 521 in addition to Windows Phone 8 Update 3. Between the two you can look forward to new features and functions like Driving mode, Bluetooth fixes, screen lock orientation, Glance screen improvements and more!
After you update you should be rocking software update 3056.0000.1404.0034 on your Lumia 521.
Looks like the rollout has just begun, but you can check to see if the update is available for your Lumia 521. Just head into your phone’s settings, hit phone update, and start to the process to check if there’s an update available for your phone.
Be sure to hit up the Lumia 521 forums to talk amongst your brethren if you have any issues.
