A new build of Windows 10 Mobile, 10586.122, is said to begetting tested inside Microsoft. This is a cumulative update, which normally means that there is nothing new going on. However, Microsoft Edge (which is the browser that replaced Internet Explorer) now supports Word Flow in the address box. This is something we’ve already seen in build 14267.
Windows 10 Mobile at one time was expected to roll out this coming Monday, which happens to be the earliest when we can expect this new build to be available. Instead, Microsoft now says that many Windows Phone 8.1 models are going to need a firmware update before they can be loaded withWindows 10 Mobile. And we still don’t have a date when to expect Windows Phone 8.1 models to start receiving the update.
Previously, Microsoft said that certain models, like the Lumia 430, Lumia 532, Lumia 535,Lumia 540, Lumia 640, Lumia 640 XL, Lumia 735, Lumia 830 and Lumia 930 would get first crack at the Windows 10 Mobile update.
