When asked by a fan on Twitter if a new mobile build was going to be released today as well, Windows Insider head Gabriel Aul responded:
" We're focused on the broad delivery of 10586 to customers right now, it will be a few more days before a new Mobile build."
While Windows Insiders will have to wait until at least early next week for a new Windows 10 Mobile build, our sources have told us that a version of the OS has been sent to wireless carriers for testing. Officially, Microsoft says the over-the-air updates for Windows 10 Mobile will begin sometime in December.
