We started this week with a story that grabbed plenty of attention. It was a report from Billmonitor.com that claimed we in the UK were wasting almost £5 billion every year by choosing the wrong mobile tariffs. Although I remained a little cynical about some of the detail, there's no doubt that many consumers could be better off if they switched tariff - or even network.

Kaspersky Lab has recently released pan-European research that shows many people feel more secure using smartphones to surf the internet than PCs... yet those people are less likely to have security software on their phones than on their computers.

In this week's podcast we talk to David Emm, senior security researcher at Kaspersky Lab UK, about this research.

Front-line police officers 'on the beat' will soon only need a few seconds to check whether a mobile phone has been stolen. A new process developed by the National Policing Improvement Agency comes into effect on Monday, giving officers the ability to directly access the National Mobile Phone Register from a handheld device.

Around 54,000 officers across the UK currently use handheld computers in their work.

The UK mobile industry is losing up to £140 million a year on premium rate fraud, according to BillingScore.

It says network operators take around 30% from billing charges to cover fraud and bad debt, which means the cost of fraud affects all the players in the mobile industry, including SMS wholesalers, aggregators, content providers, retailers and consumers.

Multiplatform mobility company Good Technology has enhanced its Good for Enterprise product to include a secure web browser. It means that mobile users can now access intranets and other web-enabled enterprise applications  without worrying about the security of the information they're sending and receiving.

Good for Enterprise already offers secure email access across a range of mobile operating systems, along with 'remote control' of device functionality by IT administrators.
