Right now the countdown to Windows 10 and its General Availability (GA) on 29 July is in full swing so all the attention is focused on the PC version of the soon to be released operating system.
On the mobile side of the house things have been quite static for nearly two weeks since build 10166 for Windows 10 Mobile was released for Fast Ring Windows Insiders.
There have been quite a few app updates over that time frame but no new builds however, today that same build has been made available for the Slow Ring side of the Insider program.
One piece of advice if you are on a previous build of Windows 10 Mobile. Be sure to download the Windows Insider app to your phone and select the Slow Ring for your device.
The mobile OS is different to the one we have been using on PC's which will automatically find the Slow ring updates. By downloading and enrolling in Slow Ring through the Insider app you will be able to see this build for your device.
