The latest company to join the mobile ‘personal broadcasting’ scene is Spreaker. It’s aiming to do for audio what Twitter does for text and YouTube does for video - and it’s just released its iPhone app.

An Android app is expected shortly.

This week sees Iain taking a rare break from The Fonecast, so it’s up to Mark and James to hold the fort. They start with Nokia’s Windows Phone announcement before moving on to Visa Europe’s big investment in mobile payments, Sony’s split with Ericsson, Samsung’s smartphone success, a new design-led BlackBerry and some wide-ranging patent news from Apple.

Atria Books, part of the Simon & Schuster publishing family, has released what it’s calling the first-ever smart book. A thousand copies of ‘The Impulse Economy’ by Gary Schwartz will have an NFC sticker attached, providing a web link to book-related content.

Hmmm. That’s not really a smart book, is it?  The same kind of logic means my NFC credit card turns my wallet into a ‘smart wallet’ and transforms the pocket of my jeans into ‘smart jeans’. It means my NFC-equipped smartphone is a smart smartphone.

With Iain away this week, Mark and James discuss the week's mobile industry news - from Nokia's new Windows Phone handsets to Samsung's success and a multi-million pound investment in mobile money.

Nokia and independent WiFi provider Spectrum Interactive are trialling a free WiFi service on some of the busiest streets in London, including Oxford Street and Tottenham Court Road.

It’s available from today for the rest of the year from hotspot locations in 26 telephone boxes owned by Spectrum Interactive. If the trial proves a success, the companies plan a large-scale rollout across London from early 2012.
