We're celebrating the seventh anniversary of The Fonecast this month with a handful of our favourite interviews from the early years.

You'll hear Ben Whitaker from Masabi, Truphone co-founder James Tagg, former Olympic athlete Steve Backley OBE and online banking pioneer Steve Townend.

This week's podcast begins with a report about a delay - or perhaps even cancellation - for the UK launch of HTC's Facebook phone, the HTC First.

We then move on to Vodafone's results, an Android app scare for Sky, Samsung's successes, contactless payments, potentially life-saving QR codes and an uncomfortable story about a smuggled mobile phone.

Visa Europe says the adoption of NFC contactless payments has reached a ‘critical point’ across Europe.

More than 19 million transactions took place in March 2013, driving the total spend on contactless cards and smartphones equipped with a Visa payWave app to over €1 billion (£856 million).

Telefónica Digital and Samsung Electronics have announced a global deal that’ll add direct mobile billing to the Samsung Hub and Samsung Apps services.

It means that Telefonica customers will be able to charge the price of apps and other content to their mobile phone bill.

A new survey from the USA has published some of the reasons why consumers are giving up on mobile shopping transactions.

The 2013 Mobile Consumer Insights study, which was conducted on behalf of payment technology company Jumio, found that 68% of smartphone and tablet owners had attempted to make a purchase on their device. However, 66% of these people had failed to complete a mobile-based transaction.
