Nokia's old ovi.com is undergoing a butterfly-like transformation, it seems. ovi.com, as of right now, simply redirects to maps.nokia.com.

Nokia Store has also undergone the rebranding and is more user-friendly and faster, and we continue to work on changing the brand from Ovi to Nokia on various channels, including this blog
