Nokia has started to rollout a Windows Phone 7.5 Refresh (Tango) update to its existing Lumia 800 and 710 handsets. The update introduces several new features, including Internet sharing and a flip-to-silence option. Lumia 800 and 710 users will also be able to download optional Camera Extras, Contact Share, and Play To apps after the latest Windows Phone update is applied.

Existing Lumia 900 and 610 handsets already have the latest Windows Phone updates and flip-to-silence, but 800 and 710 users can obtain the update from Zune on a PC or the Windows Phone Connector software on a mac. The update is fairly minor, with the exception of internet sharing, adding MMS improvements and a new GPS location icon.
