A new Guinness World Record has been set for the fastest text message on a touchscreen mobile phone. It's a new category – previous attempts have used a physical keypad – and was set using Swype technology on the Samsung Omnia II smartphone.

The record was set by Franklin Page, who's previously worked for Swype. He wrote the official world record phrase in 35.54 seconds: "The razor-toothed piranhas of the genera Serrasalmus and Pygocentrus are the most ferocious freshwater fish in the world. In reality they seldom attack a human".

New image sensors from California-based InVisage Technologies could deliver up to four times higher performance than today's mobile phone cameras. The company says its new QuantumFilm sensors outperform silicon-based image sensors by capturing between 90% and 95% of available light, as opposed to the 25% captured by the average digital camera.

Its QuantumFilm sensors are the world’s first commercial image sensors to use quantum dots; tiny nanometre-sized semiconductors that capture light.

We’ve laughed in the past about coffee cups from the United States that warn about the coffee they contain. Now there seems to be a similar movement against mobile phones that connect to the internet.

Today, in a speech about 'Building Britain's Digital Future', Prime Minister Gordon Brown talked about government plans that would see Britain becoming the world leader in the digital economy. He also committed to bringing 'superfast broadband' to everyone.

In addition, Gordon Brown announced a new free 'Number 10' iPhone application to deliver news, video and audio from the Downing Street website.
