After Monday's rumor that Windows Phone 7.8 was rolling out to the Lumia 800, Nokia set the record straight.
A Nokia exec has addressed the competition, but is his tweet also hinting at an unknown new Lumia device?
According to some recent stats, Windows Phone experienced a 24% growth in Europe during July this year.
Credit rating agencies have downgraded Nokia's long-term outlook to junk status after second quarter losses.
These devices include tablets, "hybrid" smart mobile devices, and handsets with "different form factors" from what's currently on the market.
