The next iteration to Lumia Cyan firmware will start rolling out soon for Windows Phone users.

The confirmation comes from a posting by the official Lumia Twitter account, which states in a reply to a query regarding the Lumia Denim, that the update will be available soon following the testing and network operator's approval.

Not all Lumia Windows Phone 8 devices will receive the update. Besides, the operator devices usually take a long time to get approval. Regardless of this, the mention of 'soon' in the tweet conveys a positive sign.

The Lumia Denim firmware along with Windows Phone 8.1 Update 1 is expected to become available starting with Lumia 830 and Lumia 930, reports NokiaPowerUser. The Lumia 1520 is said to be the next contender to get the update.

As for other Lumia devices, the Lumia 925 and Lumia 1020 are affected with random freezing issue after installing the Windows Phone 8.1 update. Microsoft has acknowledged the issue, which is due to a power regulator logic failure, and has said that a fix is in the works and will be released with the next software update.

As the next software update is Lumia Denim, this hints that the update will be available for Lumia 1020 and Lumia 925.
