Nokia recently made a beta version of its Nokia Chat application available to Lumia Windows Phones. The beta application, which Nokia already offers to its S40, Symbian, and Asha platforms, lets Nokia Lumia device owners conduct instant messaging conversations with one another.
It also hooks into Yahoo Messenger and lets users easily share their location. The app includes support for Live Tiles, push notifications, lock screen notifications, and voice commands.
Nokia Chat Beta is free to download from the Windows Phone Store.
