Nokia and Microsoft have today started the roll out of the Tango (8779) OS update and new firmware (12223) update in AT&T and Canada for Lumia 900. Update should be available right now when you connect your phone to Zune Desktop.
The most visible item that this update delivers is one of the newest features of the Windows Phone platform: the intuitive “flip-to-silence” function when receiving an incoming call.
There are also enhancements to the performance of the startup sequence – most notably providing a more reliable boot sequence following a full depletion of the battery – as well as enhancements to camera performance when utilizing the popular “pocket-to-photo” feature that allows users to open the camera application on a locked device with a simple press of the dedicated shutter button.
That camera update is something people have been especially happy with as it seems to drastically improve the quality.
