Chelsea vs Man Utd to launch Sky 3D in the UK

Sky 3D is coming to homes and pubs in the UK on 3 April, with Chelsea vs Man Utd the first game to be available to the public shown in 3D. The day also marks the launch of the Sky 3D channel in homes, but this will not be showing the match – merely a showreel of selected 3D footage. After the Chelsea vs Man Utd game, Sky has vowed to show five more games in 3D and only in pubs before the end of the season – although these are to be confirmed.

Vodafone: O2 still a problem network

Vodafone has once again criticised O2's data network following a recent interview with O2 CTO Derek McManus.

It's a positive challenge. How do you ensure you have coverage?"

Project Natal needs 13 feet of free space

Microsoft has revealed that you will need 13 feet of free space in your lounge to properly play Project Natal games. That's four metres. Of space in your lounge.

10 really cool new apps and gadgets you've never heard of

Some companies come to the DEMO conference looking for investors so they can get their idea to market; others are on sale the day they go on stage. Some products sink without trace, others go on to be household names (Palm launched at DEMO). Not everything is brand new –last year Gwabbit won the coveted Demo God award, this year the Gwab-o-sphere service that works with it won again. Some of the neatest DEMO launches may never make it, but these are the ones we most want to use ourselves.

Are you addicted to your iPhone and is it screwing up your life?

Do you reach for your iPhone first thing before giving your wife a good morning kiss? Do you spend more time looking at your shiny new 3GS in bed than reading one of the growing pile of great books next to you? Do you get more excited about new apps than you do about new albums?

6 handy tools to tune up your PC

Each time you add a new game, or delete a file, your PC gets clogged with irrelevant and orphaned files. And then there's the registry, from which Windows loads up all manner of driver links and other gubbins. But many of the entries in the Registry aren't used by Windows, and loading them up slows down your PC.

How to detect and remove rootkits

A rootkit is a program that allows a hacker to come and go as he pleases, unhindered by your computer's defences. No firewall will stop him and no antivirus program will detect his activities. Rootkits subvert the way the operating system works to make it lie about the processes, files, Registry entries and kernel modules that might give away the rootkit's presence to humans and antivirus software.

What Silverlight 4 means for you

Canon EOS 550D
