PC Advisor's top five tweets of the week

There's been plenty of tech issues for Twitter users to tweet about over the past seven days, from Nokia launching a free Wi-Fi network in London to Ofcom's revelation that 27 percent of the UK can't get access to 3G signal from all of the UK's five major mobile networks. Here's our five favourites tweets of the week.

Nokia announced this week it had joined forces with Spectrum Interactive to bring free Wi-Fi to London. Under the trial, which began this week and will run until the end of the year, 26 streets across the city, including Oxford Street, Tottenham Court Road and Sloane Square, will offer Wi-Fi connections of 'up to' 20Mbps thanks to equipment installed in street-side phone boxes owned by Spectrum Interactive. Users can simply locate the Wi-Fi network on their device and then accept the terms and conditions before they begin browsing, there is no need to register to use the service.

"Great news for the capital. Slightly annoying for the rest of the UK. 'Nokia and Spectrum Interactive bring free Wi-Fi to London," we tweeted.

However, while the UK's capital is being given free Wi-Fi, Ofcom was quick to point out that 27 percent of homes and businesses in the UK can't receive 3G signal for all of the UK's five major networks. The announcement was part of research that featured in the regulator's first 'Communications Infrastructure' report which must be submitted to the Secretary of State for Culture, Media and Sport every three years.

Deputy news editor CarrieSkinner said: "27 percent of UK can't receive 3G signal from all five of the UK's major mobile networks".

If you run a business from your home, you may wish to run your personal and professional PCs and laptops separately. So we got our Helproom expert to explain just how to run two networks from a single connection.
"Ever wanted to run two networks from the same router. Here's how you do it," we said in a tweet.

Kodak' recently introduced its Hero series of multifunction printers. You'll pay a bit more up front for these smart looking all-in-ones - but you'll get your money back in the long run. The Kodak Hero 9.1 and its sibling printers are cheap to run whether you calculate it by cost per page or total ink replacement.

"Kodak Hero 9.1 review - a high-end all-in-one printer that could pay for itself in two years," said Editor MattJEgan.
Tiny add-on turns iPhone into hand projector, throws 25-inch screen from 1 meter

We absolutely love this tiny projector that plugs into an iPhone's docking slot and can throw a 25-inch image about a meter away. The projector, which has gone on sale in Japan and China, weighs just 32 grams and is about the size of half an iPhone. Its tiny LED lamp runs off the phone's battery and generates 320-by-240 resolution at a brightness of 10 lumens.
