A new forecast from research specialists Canalys shows the smartphone market is set to recover next year. Worldwide shipments declined by 12% last year but that decline is expected to slow to 5% this year.

Vodafone Group plc and CK Hutchison Group Telecom Holdings Limited have agreed to combine their UK telecommunication businesses, respectively Vodafone UK and Three UK. The merger will create a large new network operator to compete with Virgin Media O2 and EE.

UK mobile payment service Paym will close on 7th March 2023. The service, which allowed users to make and receive payments using their mobile phone numbers, was launched in 2014.

I noticed a new phenomenon at Mobile World Congress this year: Beer O’Clock. Come 5pm Monday through Wednesday, companies with larger booths would break out the Cerveza, Vino, Cava and a small number of Orange juices. All very sociable and fun… until the music started.

We start this week's podcast by talking about an Android security risk - before moving on to new 4G services from EE, a drop in Nook tablet prices and a couple of quarterly results that disappointed the stock market.

In addition we discuss insurance complaints, Bluetooth Smart technology, a new multi-million investment in Shazam and some research about the future of apps.

Although last week's Apple iPhone 5 announcement dominated the headlines, there's still plenty more to talk about.

We have a prediction about the billionth Android handset, we look at Acer's cancelled smartphone launch and we discuss the growth of mobile messaging.

This week's edition of The Fonecast starts with news that Motorola Mobility is to lose around a fifth of its staff worldwide. There's also more reorganisation at Nokia, which is passing its Qt software business to Digia.

In addition we're talking about a new US partnership between Starbucks and Square, some good news for Research In Motion, a worrying report for Samsung and a major milestone for Shazam.

We're squeezing plenty of news into this week's podcast, starting with a warning about so-called 'unlimited' data tariffs and ending with a new online gallery that hopes to put art into smartphones.

This week we talk to Shazam CEO Andrew Fisher about the mysteries of mobile music discovery. And, as usual, there's a look at the week's mobile industry news - from T-Mobile's data leak to the launch of O2-backed virtual network giffgaff.
