Today's Tech: Windows Phone OS approaches double-digit share in Europe and John McAfee develops NSA blocking device

As BlackBerry continues its slow, painful decline, it appears that Microsoft's Windows Phone operating system is continuing to pick up steam. According to new data from Kantar WorldPanel ComTech, Windows Phone is approaching double-digit market share in Europe, landing at 9.2 per cent across Britain, Germany, France, Italy, and Spain for the three months ending in August. In Germany, it is within one percentage point of iOS, and has already hit double digits in Great Britain and France.

It turns out you can't keep an eccentric tech entrepreneur down. John McAfee returned to the spotlight this week with a new invention aimed at blocking NSA surveillance. Unveiled Saturday in San Jose, the pocket-sized "D-Central" prototype is expected to be complete and ready to communicate with smartphones, tablets, and other devices within six months.The sub-$100 (£61) router's three-city-block range (a quarter mile in the country) will allow users to connect to the Internet from behind a government-proof wall, providing an anonymous experience compatible with the Android and iPhone platforms.

The government has announced proposals for faster wireless broadband on the UK's train network, meaning that by 2019 70 per cent of commuters should benefit from Internet speeds of up to 50Mbit/s. The transport secretary, Patrick McLoughlin, unveiled his plans on Monday that in the short-term should result in improved wireless services by as early as 2015. Using their existing communication network, Network Rail has pledged to fund the project, increasing trackside mobile masts and signal boosters on train carriages.

A former Microsoft privacy adviser has lost faith in the security of its technology after evidence of collusion with the US National Security Agency [NSA]. Caspar Bowden, who was head of privacy policy in 40 countries at Microsoft from 2002 to 2011, had no knowledge of the US government Prism programme during his time at the company. "I don't trust Microsoft now," he told a conference in Lausanne, Switzerland according to the Guardian, before adding that he only uses open source software in order to be able to pore over underlying code whilst adding that he's not carried a mobile phone for two years.
