Mobile device and OS maker Jolla has announced that its first smartphone will be released on November 27 in Finland.

The company revealed the release date at the Slush conference in Finland today, adding that it would first go on sale through the mobile operator DNA’s pop-up shop in Helsinki.

The button-less handset runs its own Sailfish OS which is based on Mer, an open source operating system found in a range of devices, from phones to domestic connected devices.
