Microsoft VP: No more Windows 10 Mobile builds for the Insider program before next week's event12
Windows Phone isn't expected to be ready until late this month. The new handsets will probably not be launched until November, although they reportedly will be available for consumers to try out starting on October 26th when the New York City flagship Microsoft Store opens its doors. The store is made up of five stories located at 677 Fifth Avenue.
At present, Windows 10 Mobile build 10536 appears to be the best version of the OS for most Lumia owners. According to Aul, after the event it looks like there will be some more builds made available before a final decision is made.
