Microsoft has confirmed that the Windows 10 Mobile version of the Anniversary Update won't be rolling out today. The OS update is expected to be released sometime 'in the coming weeks"

While the PC and tablet version of the Windows 10 Anniversary Update has started its worldwide journey to all of its devices, it looks like owners of Windows 10 Mobile phones will have to wait a bit longer. If you are a member of the Windows Insider Program, you already have the current 14393 build of Windows 10 Mobile, according to Insider leader Dona Sarkar:

#WindowsInsiders: if you have 14393 you have the latest Mobile build. So relax. We're now going offline to do a #WINsider4Good project. — Dona Sarkar (@donasarkar) August 2, 2016

In addition, a few days ago, Microsoft posted this update for Insider members in the Feedback hub:

Earlier this year when we launched Windows 10 Mobile, we announced a series of changes to Windows 10 Mobile Insider Preview Program, including details of our launch of Windows 10 Mobile as well as changes to the supported Windows 10 Mobile Insider Preview devices. With the upcoming release of the Windows 10 Anniversary Update, the Release Preview ring is moving to Windows 10 Mobile Insider Preview build 14393. This change will have some impact on unsupported devices: As stated before, unsupported devices will not receive any builds or updates newer than 10586.x. Unsupported devices will not be able to select any Windows Insider Preview rings in the Windows Insider app. Updates to apps and services may not be available for unsupported devices and in some cases may limit certain experiences. Unsupported devices can still use the Windows Device Recovery Tool to recover to Windows Phone 8.1, but will not have the option to return to Windows 10 Mobile. As always, we appreciate our Insiders and thank you for your participation in the Windows Insider Program.

Naturally, when the Windows 10 Mobile rollout of the Anniversary Update actually begins, we will post the news ASAP.
