There's a diverse collection of mobile-related news in this week's 30-minute podcast.

We start with the new Twitter music service before moving on to discuss quarterly results, patent licensing, wireless charging, advertising and mobile payments... before ending with a curious report about app-controlled underwear.

The past few days have seen the arrival of two familiar seasons. Not only has the sun peeked its head from behind the clouds in an approximation of Spring but the mobile industry has been releasing its quarterly results.

Visa Europe is enhancing its mobile payment service with two new features: Multi-Currency and Immediate Payments. They’ll be available to any of the organisation’s member banks and payment service providers.

Immediate Payments is being launched in the UK this week, making it possible for consumers to receive money sent from other mobile phones in less than 30 minutes.

Vodafone India has partnered with ICICI Bank to launch the M-Pesa mobile money transfer and payment service in India. It’s estimated that approximately 700 million people in the country have no access to conventional banking.

M-Pesa was first launched in Kenya in 2007, allowing customers to send and receive small amounts of money on mobile phones.

In today's podcast we're talking about Samsung's new Galaxy S4 smartphone, BlackBerry's record-breaking purchase order and Intuit's mobile payment service.

There's also a discussion about the changes at ST-Ericsson, a new CEO coming to ARM, Vodafone's sponsorship plans, management moves at Android and the 2013 Mobile News Awards.
