The Lumia 800 (as well as the Lumia 710) is expected to receive a firmware update sometime soon to enable WiFi tethering on the handset, a feature that was introduced in the Windows Phone "Mango" update. We previously reported that Plaffo has confirmed a tethering update is on the way and all Lumia handset owners will be able to utilize the Internet sharing functionality - dependent on their carrier of course.

It would appear (looking at the photo above) that the feature is already active on some handsets, according to a We Love Windows Phone.hk reader. While it's not yet known when the said update will be pushed out to consumers, it's a positive sign to see Internet sharing actually on a Lumia 800.
