Microsoft already announced that Windows 10 will be releasing on July 29th, but what about Windows 10 Mobile? Well, if you are holding on tight to your Windows Phone 8.1 in hopes of a better experience with Windows 10 Mobile, you'll have to wait for a couple of months.

A slide showed by a Microsoft spokesperson and obtained by Neowin reveal that Microsoft plans to release Windows 10 Mobile sometime in September this year. Both enterprise and consumer versions of Windows 10 Mobile will be available next quarter, according to the leaked slide.

This information was meant for OEMs, and not end consumers, as Neowin points out in their article. It could be that Smartphones running Windows 10 out-of-the-box won't be released until Q4 2015. Meanwhile, Microsoft may release the update for existing Windows Phone 8.1 devices around the same time.
