Starting with the Lumia 520, the Nokia smartphone is accepting the Windows Phone 8 Update via mobile carriers O2 and Vodafone. A "Country variant" carrier is also rolling out with the update.

With the Lumia 620, Vodafone has distributed the update, while T-Mobile is in the "Coming soon" phase.

The Lumia 720, as of Sept. 16, is in the "Waiting for approval" stages with carriers O2, Vodafone and a "Country variant."

The Lumia 820's Windows Phone 8 Amber Update is available via carriers O2 and T-Mobile. The Lumia 820 update, however, is in the "waiting" phase with Vodafone.

T-Mobile has rolled out the Amber Update for the Lumia 920, while Vodafone is "Waiting for approval."

Nokia has defined the term "waiting for approval" as undergoing final testing with either the specific country or mobile carrier before approval. The definition for "coming soon" means the update has been approved but is in "final pre-release checks."

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."

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!"
