Nokia Lumia 800 just topped the best-seller chart for KPN, one of the biggest carriers in the Netherlands. It has overtaken the former leader, the iPhone 4S, which is in second place.

The Nokia Lumia 800 is doing pretty well in France too. A Windows Phone app developer tracked the downloads of their app and saw the Lumia 800 shoot past the other WP7 phones over the last month. And the Lumia 800 has only been on sale in France for one month.

Everyone knows it is been a tough year for Nokia, as the world biggest handset maker tries to turn the ship around and get back some momentum through itsalliance with Microsoft and a range ofshiny new Lumia handsets.

Even the company most hardcore supporters that is, users in its home territory of Finland seem to be defecting to rivals, with new figures from IDC showing that it has lost more than half of its smartphone market share there over the last 12 months.

According to a Finnish language report from Helsinki Taloussanomat, Nokia share of the smartphone market for the third quarter of 2011 has dropped to 31 percent thats down from 76 percent the same time last year.

O2 UK users can now add the Nokia Lumia 800 to the list of ideas for a holiday gift. The official site of the British carrier lists the Windows Phone handset as "Coming soon: December".

That is as specific as their site got, but their Twitter account pinpoints December 9 as the exact date that the Lumia 800 will go on sale. There is nothing on the color options though only the black one is featured on O2 site and there is no mention of the other colors.

Nokia is planning to hold a huge event to celebrate the birth of their first Windows Phone smartphone. The company sent out invitations for a huge light show that will use the Millbank Tower on the Thames as a screen.

On November 28 Nokia will be employing 16 projectors, 800 windows, 200 workmen and 3 D3 servers to create "the biggest video-mapping project ever attempted in the UK" . The star of the show will be deadmau5 DJ, who will play an exclusive set to the backdrop of an amazing 4D animation.
