Anti-virus software company Kaspersky Lab is warning of an application that secretly uploads a user’s phonebook to a remote server, from where ‘spam’ SMS messages are sent.

The app, called ‘Find and Call’, was available in iOS and Android versions via the Apple App Store and Google Play.

Two years after its formation at Mobile World Congress, the Wholesale Applications Community has launched the beta version of its in-application billing Network API.

The service, which enables customers to pay for digital goods via their mobile bill, is currently supported by AT&T, Deutsche Telekom, KT, LG U+, Telefonica Group, Telenor Group, Telekom Austria Group, SKT and SMART Communications.

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.

In this week's edition of The Fonecast we're chatting to David Emm, senior security researcher at Kaspersky Lab UK, about the security threats facing mobile phone users.

We also discuss the latest report from mobile tariff comparison site Billmonitor, we talk about Tuesday's Symbian news, we look at a new unlimited internet deal and we discover a clutch of MVNOs.
