iPhone 4S announced by Apple

Apple has unveiled the latest iteration in its iPhone range, but there was no sign of the widely rumoured iPhone 5.

The iPhone 4S, as the new model will be known, boasts an improved camera and significantly extended battery life.

It will run on the latest iOS5 operating system, which is set for release on 12 October.

The event was the first major announcement for new CEO Tim Cook who took over from Steve Jobs in August.

The iPhone 4S, to be released on 14 October, will be available in 16GB, 32GB and 64GB models - in both black and white.

HTC to release urgent privacy fix

HTC is to release an urgent update for several of its smartphones to fix a vulnerability which could leave personal information at risk.

The Android Police blog discovered that a user's GPS location and call logs could be easily accessed by net-enabled apps.

After investigating, HTC admitted the flaw could be "exploited by a malicious third-party application".

It said affected users will be notified of the update automatically.

"HTC is working very diligently to quickly release a security update that will resolve the issue on affected devices," a spokesperson said.

Users will be able to download the fix over-the-air.

The company has not yet confirmed exactly which models are at risk, but it is understood that the EVO 3D, EVO 4G, Thunderbolt and potentially the Sensation range are all susceptible to the vulnerability.

Until the patch is released, the company urges users to "use caution when downloading, using, installing and updating applications from untrusted sources".

The flaw relates to a particular file which contains a vast amount of personal information including GPS location history, SMS data, phone logs and e-mail accounts.

"Start Quote

A third party malware app exploiting this or any other vulnerability would potentially be acting in violation of civil and criminal laws. "

End Quote HTC spokesperson

Apps can gain access to the file by requesting permission to access the internet - a common occurrence for apps that allow the posting of top scores or messages on social networking sites.

HTC said they have found no evidence that this flaw has been exploited for malicious purposes, but conceded it does pose a threat to the protection of the user's information.

The statement read: "In our ongoing investigation into this recent claim, we have concluded that while this HTC software itself does no harm to customers' data, there is a vulnerability that could potentially be exploited by a malicious third-party application.

"A third party malware app exploiting this or any other vulnerability would potentially be acting in violation of civil and criminal laws.

"So far, we have not learned of any customers being affected in this way and would like to prevent it by making sure all customers are aware of this potential vulnerability."

The company said the patch will be released after a short period of testing, and users are urged to download the update promptly.

Artem Russakovskii, the blogger who made the flaw public, welcomed the quick action by HTC, but said he still had concerns over the manner in which large amounts of personal data are kept in the single file.

He wrote: "While I applaud HTC's desire to fix the situation quickly, I do have to wonder whether the patch will simply apply some sort of an authentication scheme to the service while letting it continue collecting the same kind of sensitive data to be potentially reported back to HTC or carriers."

Apple expected to launch iPhone 5

Apple is expected to launch the fifth version of its best-selling iPhone today.

Journalist have been invited to a "Let's talk iPhone" event at its California campus due to start at 13:00 PDT (18:00 BST).

Doubts surround how different the iPhone 5 will be to its predecessor though some do expect big changes.

The launch will be hosted by Tim Cook, now Apple's full time boss following Steve Jobs' retirement in August.

As ever with Apple launches, exact details of product features will not be known until the event. Expert opinion is divided with some expecting significant changes.

"We're expecting a flagship, high tier product to cement the iPhone's position as the must-have device," said Ben Wood, director of research at analysts CCS Insight.

Gadget site Gizmodo took a different line and said there was only a 10% chance of seeing a new iPhone. Instead, it said, the iPhone 4S will be the new model and it will be cheaper than its predecessor.

Others say the cheaper model will be aimed at Asia, one of the few places where the smartphone has room for growth.

Rumours are also circulating that Steve Jobs will make a cameo appearance even though Mr Cook is expected to be the launch compere.

The event is the first since Mr Cook became official head of Apple. Before now he was an interim boss who oversaw day-to-day running of the company when Mr Jobs was on sick leave.

History lesson

The iPhone 4 debuted 15 months ago and the hiatus between that launch and today marks one of the longest periods without a new model in the history of the device. All previous versions, bar the first, have been unveiled in June.

Mr Wood said this might reflect the complexity of the task Apple set itself when getting the iPhone working the iCloud service. This acts as a network-based backup and synchronisation system for Apple's smartphones and tablets.

"The announcement is definitely more about the holy trinity of device, software and applications, and services to which iCloud adds a completely new dimension," he said.

The use of iCloud would help Apple stay one step ahead of rivals, especially HTC and Samsung, who were fast getting their own hardware to match the capabilities of the iPhone, said Mr Wood.

Apple will also be keen to put behind it the troubles that dogged the iPhone 4. Incorporating the phone's antenna into its case was blamed for causing a loss of reception. The problem led to the company offering free cases to owners to combat the reception loss.

The launch of the phone is important to Apple which is keen to capitalise on its growing share of the smartphone market. It faces strong challenges from Google's Android mobile phone operating system which, figures suggest, has become the most popular among new phone buyers in the US.

The ability of the phone to be activated and updated without connecting to a PC would help this push, said Mr Wood.

One strong competitor for the smartphone market is South Korean electronics firm Samsung. It produces phones that use Android as well as models that use its own operating system called Bada.

Apple and Samsung are locked in litigation around the world over who owns the rights to use many technologies found in both smartphones and tablets.

The court room clashes have led to a ban on the Galaxy Tab 10.1 in Germany and a ban on the sales of some Galaxy smartphones in the Netherlands.

In Australia, the row meant a delay to the launch of the Galaxy Tab 10.1. In the most recent development in that row, Apple has reportedly rejected Samsung's offer of a deal to settle the case.

HP completes buy-out of Autonomy

<!-- S MD_WIDGET --> <!-- E MD_WIDGET -->

Hewlett-Packard has completed the $12bn (�7.8bn) buy-out of UK software firm Autonomy, despite the departure of the man who initiated it.

Leo Apotheker was replaced as HP chief executive last month amid falling sales and a share price collapse.

The Autonomy deal was part of a massive overhaul of the troubled US computer giant unveiled by Mr Apotheker.

But plans to spin off its core PC business received a thumbs down from the market.

HP's shares have fallen 47% this year, making it one of the worst performers in the Dow Jones index of leading US companies.

The purchase price for Autonomy was also widely criticised by market analysts as too high, but British takeover rules made it almost impossible to cancel the bid.

Meg Whitman, the former head of eBay who replaced Mr Apotheker, said shortly after her appointment that the deal would still go ahead.

The UK firm's head, Mike Lynch, later got into a colourful spat with HP rival Oracle, who claimed that Mr Lynch had sought a rival bid from them and been declined.

Oracle's chief executive Larry Ellison described the asking price as "absurdly high".

HP's shares closed 1.1% lower on Monday, outperforming the wider market.

BT suffers major broadband outage

BT has confirmed that a "power failure" at a major exchange in Birmingham is causing problems for broadband customers across the UK.

Customers have reported problems from as far afield as Belfast, Edinburgh, Swansea and London.

Many users have taken to Twitter to complain that the company is not answering its helpline.

BT has told the BBC it has been made aware of the issue and is working hard to get information to customers.

In a statement, the company said: "We can confirm that, as a result of a power failure at one of our major exchanges, some customers may currently be experiencing loss of broadband service.

"Our engineers are on-site and the majority of customers' service has already been restored. We are working to restore service to remaining customers as soon as possible this afternoon.

"Should any customers continue to experience difficulty in accessing their broadband service, they are advised to turn their Hub or modem off and on again."

The outage has affected both business and home customers.

Carl in Bedford contacted the BBC, saying: "We have lost both our business lines at work and causing us lots of lost revenue as we can no longer do our scheduled remote work on our customer sites.

"It is shocking that a small power issue 150 miles away in Birmingham can have such a huge affect on business customers elsewhere."

Other users reported problems in many other places including Cambridge, Brentford, Wolverhampton and Cornwall.

Facebook adds phishing safety net

Facebook have stepped up their battle against phishing and malware scammers by partnering with security firm Websense.

As of next week, users will be warned if they are about to be taken to a malicious website.

The social network has suffered to date as many of its 700 million users unwittingly click on dangerous links supposedly posted by their friends.

Such attacks usually trick users into sharing passwords or data.

Facebook already tells users if they are about to visit an external site, but the current set up makes no distinction between friendly and dangerous sites.

The new technology will present a warning screen whenever it suspects a page poses a threat to the users, giving details of the risk.

From here, users are encouraged to return to the previous page.

If they wish, users can continue to the intended page, albeit very much at their own risk.

'Profitable target'

Both Facebook and Websense will hope the extra measures will be enough to deter potential scammers from focusing their efforts on the network.

Scams regularly catch out hundreds of thousands of users at a time.

"Start Quote

As more of these 'friend in the middle' attacks happen, you start to trust your friends less."

End Quote Spencer Parker Websense

"There's over 700 million users on Facebook," Websense's Spencer Parker told the BBC.

"As a piece of real estate, it's extremely profitable to be targeted by malware writers."

The protection will be powered by Websense's "Threatseeker Cloud", a system which stores a database of known malicious URLs.

The system can also detect unknown dangerous URLs by assessing threats in real-time.

This means harmful URLs can be blocked even before they are known to the company - cutting off a key tactic used by phishers in which constantly changing URLs fool database-driven protection.

In addition, the system will "follow" links made using popular URL shorteners - such as bit.ly and ow.ly - to verify their safety.

Due to the nature of how we interact with our friends, Mr Parker says phishing attacks on Facebook are much harder to prevent than other commonly used techniques.

"One of the things with Facebook, of course, is that you have that element of trust in a social network. If one of your friends posts something, you automatically trust it more than if it just received as a spam email.

"As more of these 'friend in the middle' attacks happen, you start to trust your friends less."

HTC &#39;investigating&#39; security flaw

HTC is investigating claims that a security flaw in several of its mobile phones means personal information is being exposed.

The Android Police blog says a file containing a user's GPS location and email addresses can be easily accessed once internet permissions are granted.

Several models are said to be affected, including EVO 3D, EVO 4G, Thunderbolt and potentially the Sensation range.

HTC said it is looking into the claims "as quickly as possible".

"HTC takes our customers' security very seriously, and we are working to investigate this claim as quickly as possible," the company said in a statement.

"We will provide an update as soon as we're able to determine the accuracy of the claim and what steps, if any, need to be taken."

Systems administrator Trevor Eckhart produced a proof of concept app designed to show off the vulnerability.

By simply asking a user's permission to access the internet - a request popular with games apps seeking to post scores online - the app was able to access a file named "HtcLoggers.apk".

"Start Quote

It's like leaving your keys under the mat and expecting nobody who finds them to unlock the door"

End Quote Artem Russakovskii Android Police blog

The file contained several key pieces of personal information, including:

  • The list of user accounts, including email addresses
  • A log of recent GPS locations
  • Phone numbers taken from recent call logs
  • SMS data, including recent numbers and encoded messages

The Android Police blog described the risk as "like leaving your keys under the mat and expecting nobody who finds them to unlock the door".

Rik Ferguson, director of security research and communications at Trend Micro, believes the risk should be an easy one to solve.

"It sounds like something very simple to patch," he told the BBC.

"They didn't anticipate that kind of information would be of interest. It's a lack of foresight rather than lax programming, I think. It should be something relatively easy to fix."

Samsung hobbles tablet to end row

Samsung has offered to remove some features from its Galaxy Tab 10.1 as it seeks to overturn a court-imposed sales ban in Australia.

The ban on sales was sought by Apple which claims the tablet copies many of the iPad's patented features.

Samsung has also reportedly made an offer to settle the dispute between the two firms so it can get on and launch the tablet in Australia.

Apple said it needed time to consider the merit of Samsung's proposals.

By removing and changing features Samsung is trying to end its wrangle with Apple outside the Sydney court overseeing the dispute.

The two sides will return to court on 4 October. However, If Apple accepts the settlement offer the court case could halt and the Tab might be launched soon after.

Apple sought the initial injunction to stop the launch of the Galaxy and then asked the court to rule on whether Samsung has violated its patents.

The initial claim made by Apple mentioned 13 separate patents. However, Samsung has progressively taken out or altered functions to avoid infringing Apple's intellectual property. Now the dispute centres around only three patents.

Samsung originally intended to launch the Galaxy tablet in Australia on 11 August. This was delayed by the injunction and was scheduled for 30 September. However, the ongoing court dispute has delayed it again.

The legal row in Australia is one of many that Apple and Samsung have started around the world. They currently face each other in courts in the US, Germany and the Netherlands.

Smart cities to get their own OS

Cities could soon be looking after their citizens all by themselves thanks to an operating system designed for the metropolis.

The Urban OS works just like a PC operating system but keeps buildings, traffic and services running smoothly.

The software takes in data from sensors dotted around the city to keep an eye on what is happening.

In the event of a fire the Urban OS might manage traffic lights so fire trucks can reach the blaze swiftly.

The idea is for the Urban OS to gather data from sensors buried in buildings and many other places to keep an eye on what is happening in an urban area.

The sensors monitor everything from large scale events such as traffic flows across the entire city down to more local phenomena such as temperature sensors inside individual rooms.

The OS completely bypasses humans to manage communication between sensors and devices such as traffic lights, air conditioning or water pumps that influence the quality of city life.

Channelling all the data coming from these sensors and services into a over-arching control system had lots of benefits, said Steve Lewis, head of Living PlanIT- the Portuguese company behind Urban OS.

Urban OS should mean buildings get managed better and gathering the data from lots of sources gives a broader view of key city services such as traffic flows, energy use and water levels.

"If you were using an anatomy analogy, the city has a network like the nervous system, talking to a whole bunch of sensors gathering the data and causing actions," said Mr Lewis.

"We distribute that nervous system into the parts of the body - the buildings, the streets and other things.

Having one platform managing the entire urban landscape of a city means significant cost savings, implementation consistency, quality and manageability, he added.

"And it's got local computing capacity to allow a building or an automotive platform to interact with people where they are, managing the energy, water, waste, transportation, logistics and human interaction in those areas."

"Start Quote

That's dealt with by the building itself, with the devices very locally talking to each other to figure out what's the best solution for the current dilemma"

End Quote Steve Lewis CEO, Living PlanIT
Urban apps

The underlying technology for the Urban OS has been developed by McLaren Electronic Systems - the same company that creates sensors for Formula One cars. The Urban OS was unveiled at the Machine-2-Machine conference in Rotterdam.

To support the myriad of different devices in a city the firm has developed an extensive set of application services that will run Urban OS, dubbed PlaceApps - the urban environment equivalent of apps on a smartphone.

Independent developers will also be able to build their own apps to get at data and provide certain services around a city.

Mr Lewis said that eventually applications on smartphones could hook into the Urban OS to remotely control household appliances and energy systems, or safety equipment to monitor the wellbeing of elderly people.

It could also prove useful in the event of a fire in a building, he said.

Sensors would spot the fire and then the building would use its intelligence to direct people inside to a safe stairwell, perhaps by making lights flicker or alarms get louder in the direction of the exit.

"That's dealt with by the building itself, with the devices very locally talking to each other to figure out what's the best solution for the current dilemma, and then providing directions and orchestrating themselves," said Mr Lewis.

'Magical actions'

Living PlanIT is working with Cisco and Deutsche Telekom on different parts of the system.

Markus Breitbach of the Machine to Machine Competence Center at Deutsche Telekom said that his firm was helping to bring all the parts of the Urban OS together.

"Everybody's talking about 50 billion connected devices, which effectively means huge amounts of data being collected, but nobody is really caring about managing it and bringing it into a context - and Urban OS can do just that," he said.

"If there's a fire alarm on the fifth floor and the elevator is going to the next floor, the light will switch on - but in addition the traffic lights will be switched accordingly to turn the traffic in the right direction so that fire workers can get through.

"And this is what Urban OS is providing, this kind of solution to analyse mass data, enter it in a context and perform magical actions."

A test bed for the Urban OS is currently being built in Portugal. For its work in developing smart cities, Living PlanIT was selected as one of the World Economic Forum's Technology Pioneers of 2012.

Plastic &#39;flying carpet&#39; takes off

<!-- Embedding the video player --> <!-- This is the embedded player component -->

<!-- companion banner --> <!-- END - companion banner --><!-- caption -->

The sheet is lifted by the air packets, and propelled forwards

<!-- END - caption -->
<!-- end of the embedded player component --> <!-- Player embedded -->

A miniature magic carpet made of plastic has taken flight in a laboratory at Princeton University.

The 10cm (4in) sheet of smart transparency is driven by "ripple power"; waves of electrical current driving thin pockets of air from front to rear underneath.

The prototype, described in Applied Physics Letters, moves at speeds of about a centimetre per second.

Improvements to the design could raise that to as much as a metre per second.

The device's creator, graduate student Noah Jafferis, says he was inspired by a mathematical paper he read shortly after starting his PhD studies at Princeton.

He abandoned what would have been a fashionable project printing electronic circuits with nano-inks for one that seemed to have more in common with 1001 Nights than 21st-Century engineering.

Prof James Sturm, who leads Mr Jafferis' research group, conceded that at times the project seemed foolhardy.

"What was difficult was controlling the precise behaviour of the sheet as it deformed at high frequencies," he told the BBC.

"Without the ability to predict the exact way it would flex, we couldn't feed in the right electrical currents to get the propulsion to work properly."

What followed was a two year digression attaching sensors to every part of the material so as to fine-tune its performance through a series of complex feedbacks.

But once that was mastered, the waveform of the undulating matched that prescribed by the theory, and the wafting motions gave life to the tiny carpet.

In the paper describing the design, Mr Jafferis and his co-authors are careful to keep the word "flying" in inverted commas, because the resulting machine has more in common with a hovercraft than an aeroplane.

"It has to keep close to the ground," Mr Jafferis explained to the BBC's Science in Action, "because the air is then trapped between the sheet and the ground. As the waves move along the sheet it basically pumps the air out the back." That is the source of the thrust.

Ray hope

Harvard University's Lakshminarayanan Mahadevan, who wrote the 2007 paper in Physical Review Letters that inspired the whole project, expressed a mixture of surprise and delight at the Princeton team's success.

"Noah has gone beyond our simple theory and actually built a device that works," he told the BBC "And what's more, it behaves, at least qualitatively, as we had predicted."

Mr Jafferis points out that the prototype is limited because tiny conducting threads anchor it to heavy batteries, so it's free to move only a few centimetres. But he is already working on a solar-powered upgrade that could freely fly over large distances.

The advantage of this kind of propulsion, he argues, is that unlike jets, propellers and hovercraft, there are no moving components like cogs and gears that rub against each other.

"The ideal use would be some kind of dusty, grimy environment where moving parts would get gummed up and stop," he explained.

That said, he laughingly admits that with the existing materials, a flying carpet powerful enough to carry a person would need a wingspan of 50 metres - not the best vehicle to take on the streets just yet.

On the other hand, preliminary calculations suggest that there is enough atmosphere on the planet Mars to send floating rovers scudding over its dusty surface.

Meanwhile, Prof Mahadevan looks forward to sophisticated improvements in the near future, suggesting the approach could progress to "mimicking the beautiful two-dimensional undulations of the skate or manta ray".

You can listen to Noah Jafferis describe his flying carpet on the BBC World Service programme Science in Action.
