The European Commission has opened three investigations to examine whether tax authorities have made appropriate decisions about corporate tax paid by Apple in Ireland, Starbucks in the Netherlands and Fiat Finance and Trade in Luxembourg.

It’s launched the investigation following media reports that suggest that some companies have received significant tax reductions through ‘tax rulings’ issued by national tax authorities.

A new research report from Berg Insight shows that in-store mobile wallet payments across Europe are expected to grow from less than €100 million (£85 million) in 2012 to €45 billion (£38 billion) in 2017, which is a compound annual growth rate of 275%.

This will give mobile wallets 1.6% of all European credit card and debit card payments in 2017.

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.

Coffee chain Starbucks has partnered with mobile payment company Square to introduce the ‘Pay with Square’ app at around 7.000 US Starbucks stores. In addition, Square will process Starbucks’ US credit and debit card transactions.

Starbucks is investing $25 million in Square with its chairman, Howard Schultz, joining Square’s Board of Directors.

Earlier this year Starbucks introduced its iPhone mobile payment app to the UK - and the coffee company has now added an Android app as well.

The new Android app, which is also launching in Canada, enables customers to pay via a Starbucks Card account using an on-screen barcode. It’s also possible to manage a card account, check loyalty rewards and find local stores.

Today I've been using my mobile phone at home. For many people that’s not an unusual thing to do – but it is for me because, around here, coverage indoors isn’t particularly good. Downstairs it’s previously been non-existent. But this morning everything changed.

In Africa there is another use for mobile phones. Public Health workers in Kenya are now using mobile phones to gather health information from patients in remote areas and upload it to the internet for instant analysis at distant centers. And it is all happening thanks to Dr Joel Selanikio.

I remember a report from last year that said ‘non-smart’ touchscreen handsets – generally those without a popular operating system – would be bad news for mobile operators.

Conventional touchscreen smartphones tended to result in higher-than-average ARPU thanks to their early-adopting tech-loving users, their web-friendly browsers, their email programs, their app-friendly operating systems and their fast 3G connectivity. However, dumber touchscreen devices – those with a manufacturer’s own proprietary OS and perhaps a clumsier browser – could generate 23% less ARPU than smarter phones. So, if touchscreen dumbphones weren’t good for networks… and weren’t really good for consumers either… manufacturers wouldn’t really bother with them. Right?

Mark’s been encouraging me to write an opinion piece on the Nexus One for the last few days and I’m finally putting fingers to keyboard to share my experiences. It’s taken so long because this phone has so many features. On a positive note I could go into details about the gorgeous screen, the Android Marketplace that will out-sell Apple’s over the next 18 months, the built-in satellite navigation service and the speedy processor that makes everything run smoothly in real time. Or on a less positive note, the touch screen keyboard that sucks (think carefully about this if you’re a heavy texter or emailer, it’s even worse than the original iPhone), the lack of ActiveSync for Calendars and Tasks, no support for WMA music files or the clunky zoom functions on the web browser.

However I’m going to focus on voice dictation. Nexus One is the first phone I’ve used with this feature.

Here’s a curious thing. Firstly, Amazon creates the Kindle. It starts selling the Kindle in the USA with a mobile deal that lets users download electronic books and newspapers wherever they are. Then it starts selling the Kindle to us in the UK, although – hang on a moment – it’s not talking about a UK mobile deal. Instead it still seems to be ‘roaming’ from the AT&T network. Next comes the larger-screen Kindle DX – also roaming away when it reaches our shores. And now Amazon is talking about third-party downloadable applications for the Kindle. Yes, a mobile device with downloadable apps. Hold that thought; I’ll be returning to it.

Iain Graham, James Rosewell and Mark Bridge return to review their mobile industry predictions from last year. Which mergers, partnerships and developments did they forecast correctly... and which didn’t work out as planned?

Later in the programme, the team anticipates some of the topics that will be hitting the headlines during 2016.

Mark Bridge learns about the mobile technology trends at Mobile World Congress 2015 by chatting to James Rosewell of 51Degrees, Dr Kevin Curran from the IEEE and Chris Millington of Doro.

They talk about wearable devices, wireless charging, mobile operating systems and much more... including some of their favourite products from the exhibition.

We're taking a look back at the biggest mobile industry news stories from February 2015, including allegations that the UK's security service tried to breach SIM card security by hacking into one of the world's biggest SIM producers.

We also talk about the planned BT and EE merger, the creation of two new UK virtual networks, some acquisitions in the mobile payment arena and a new Ubuntu smartphone.

In today's programme Mark Bridge talks to Chris Millington, who's Managing Director for Doro UK and Ireland.

They discuss the state of mobile retailing in the UK, the future of wearable devices and - as you might expect - smartphones for seniors.

We're back with a month of mobile industry news, including takeover talks and takeover rumours. O2 and Three are said to be discussing a merger... but is there any truth in the suggestions that BlackBerry could be up for grabs?

We also discuss Apple's record-breaking quarterly figures, the highlights of CES and the launch of Microsoft Windows 10, as well as saying farewell to the current version of Google Glass.
