Here's an interesting one that's going to raise some eyebrows - it's an interactive multimedia preview of the Lumia 800, so you can get a tiny taster of the Metro UI on your Symbian device. While a number of die-hard Symbian fans are going to be very upset at the slightest hint of a possibility of a transition, it's another smart move from the marketing teams working on the Lumia launch.

As well as opening up the lock screen on the virtual Lumia 800, there are walkthroughs of the People hub, the Windows Phone Marketplace, and the built in Internet Explorer browser.

There's also some smart touches that let you change the colour of the phone, and an animated gallery of images.

It will be very interesting to see how many downloads this gets (and the conversion rate to new handset sales), but it does say one thing. Nokia are taking the marketing of the Lumia 800 very seriously.

Grab the download from the Nokia Store and let us know what you think.
