Tango/WP7.5 Refresh update details for Lumia 800 and 710 are out on Nokia’s official software updates page. Two new functions that come with this software update are Internet sharing (WiFi tethering) and flip-to-silence.

Internet sharing will allow you to share your mobile Internet connection over Wi-Fi with up to five other devices or computers. In effect, it turns your Nokia Lumia 800 or Nokia Lumia 710 into a mobile Wi-Fi hotspot.

As for flip-to-silence, well, you turn your phone face down, and all incoming phone calls and alerts will be silenced.

After updating, Nokia Lumia 800 or Nokia Lumia 710 will be ready to install Nokia exclusive new applications available in the Windows Phone Marketplace (Camera Extras, Counters, Contact share, PlayTo).

The Tango update’s availability map is available now on the page, and you can check whether it is going to be available for your country and product code.
