Nokia is giving away a free Nokia-branded version of the Surfcube 3D browser. The app is normally ad-supported, but will of course lack these in the Nokia version.
It also contains a cool Easter egg which can be seen during the video above.
The browser is only available to Nokia Lumia user with an Hungarian Windows Live ID and will remain available until April 15th, after which the app will still work, but will not receive any further support or updates.
If you are a Hungarian Lumia user find the browser here.
