Microsoft And Nokia Reportedly Testing Out Windows Phone 8.1 Internally

We have already heard whispers going around that since August, Microsoft has been testing out Windows Phone 8.1 internally, although information on such testing has been pretty much scant concerning the platform update itself. We already know that Windows desktops and tablets have already been on the receiving end of Windows 8.1 (aka Blue), but when it comes to the portable platform of Windows Phone 8, it has only seen the GDR3 update that has been geared in the direction of opening up new hardware setups rather than seeing the inclusion of additional software features.
