In regards to Lumia smartphones that have rolled out the Windows Phone 8 Amber Update, it will vary on the mobile carrier.

T-Mobile has rolled out the Amber Update for the Lumia 521 and Lumia 810 smartphones.

Verizon Wireless began its distribution of the Windows Phone 8 Amber Update for the Lumia 822 and Lumia 928.

Three different Lumia smartphones via two mobile carriers, however, are in the "Waiting for approval" stages. Nokia has defined "waiting for approval" as undergoing final test with either the specific country or mobile carrier before approval.

The Lumia 620, via mobile carrier Aio Wireless, is waiting for approval as well as the Lumia 820 and Lumia 920 from AT&T.

As Latinos Post reported, Nokia did not rollout the Windows Phone 8 Amber Update in one huge distribution to ensure "quality standards."

"To ensure the software update meets our quality standards, we're running multiple tests with various country variants and operators," wrote Nokia Conversations' Ian Delaney. "We make the updates available to you as soon as we complete testing. With Lumia Amber we expect to have the update arriving in all Lumia Windows Phone 8 phones by the end of September. Be patient - it's coming!"

According to Nokia, "To make sure you don't miss out on the notification, check on your phone that under Settings > Phone Update > 'Tell me when updates are available for my phone' is enabled."

The Windows Phone 8 Amber Update includes improvements to the Nokia Lumia's camera, particularly the auto focus, noise filter, and low-light photo-taking capabilities, to name a few tweaks.
