An announcement is expected from Nokia today about the launch of a touch-screen device.

Dubbed the “Tube”, the handset could be unveiled at a media and analyst event in London.

It would be Nokia’s first touch-screen since Apple launched the iPhone last year.

IMS Research recently published a report saying the current steady growth in sales of touchscreen-equipped mobile handsets will become even stronger.

It forecasts that while fewer than 30 million touchscreen phones were sold in 2007, this will surge to over 230 million by 2012.

Nokia wouldn’t comment on an unannounced product.

Reports suggest the device will be closely tied to Nokia’s Comes With Music service, which will first be released in the United Kingdom and compete with iTunes and other music services.

On September 2, Nokia announced that Carphone Warehouse will be the exclusive UK prepaid channel for the Nokia 5310 XpressMusic edition.
