Tango for Windows Phone of Lumia 900 comes Navifirm

In Europe the 900 Lumia should be marketed directly to Windows Phone Tango (Build 8773), in the States instead of the operator AT & T continues even  to sell it with Build 8112 (Mango).

In the meantime, perhaps a sign that the release of Mango Refresh is closer on all Windows phones, including Nokia servers, as signaled by the tool Navifirm, appeared the files needed to flash and update Lumia 900 to Tango. The new version of the operating system of Nokia’s servers also suggests that in addition to the Build 8773, this update should bring the firmware to version 900 Lumia 12140.
