London-based mobile phone manufacturer Kazam has announced the availability of its Trooper X3.5 Android-powered smartphone and the Life B4 feature phone at Phones 4u.

As with other Kazam smartphones, the Kazam Trooper X3.5 is offered with free cracked screen replacement within the first 12 months plus a two-year warranty.

We start this week's podcast by talking about Yahoo and Tumblr before moving on to discuss Google's recent developer conference.

There are product announcements from BlackBerry, HP and the former MeeGo developers at Jolla... and there's some interesting mobile app news as well.

Last year, the Google I/O developer conference gave us plenty of product announcements: Google Glass, the Nexus 7 tablet, the Nexus Q device and the Jelly Bean version of Android. This year’s announcements were less dramatic: a streaming music service, a Google-friendlier Galaxy S4 and some game development tools. Coincidentally (or perhaps not) Apple announced its 50 billionth app download in the middle of the event.

Mary Grant, who was CEO of the Phones 4U retail business, is reported to have left the company for ‘personal reasons’.

Mobile News reports that Phones 4U Group CEO Tim Whiting is temporarily taking on her role in addition to his own work.

At the beginning of the 21st century I moved from Vodafone to work for its Vizzavi multimedia portal, wooed by talk of context-specific advertising that would one day use a customer’s location and search history to ensure any ads were precisely targeted. And I’m not the only person who’s been seduced. Consumers, ad agencies, client companies and mobile networks have all been promised much by mobile marketing.

Yet more than a decade later that kind of sophistication seems to be lacking from most mobile marketing messages.

This week there was only one set of financial results that attracted the mainstream tech media. Apple reported the first drop in quarterly profit for several years as figures fell by 18% to around £6.1 billion. On the positive side, it made around £6.1 billion profit. It also announced dates for its developer conference in June and promised a new version of iOS.

Due to growth in staff numbers my business (51Degrees.mobi) is in the process of moving offices. Coincidentally I'm also moving our home broadband. It’s not been a pleasant experience.

This got me thinking, because a few weeks ago on thefonecast.com we discussed why Ofcom isn’t treating Mobile Termination Rates (MTR) in the same way as fixed-line termination rates. The mobile industry justifies higher MTRs on the assumption that a mobile network costs more to run than a fixed-line network. It was certainly true when the fixed costs of running a mobile network had to be shared across a relatively small number of customers, even if they did pay a fortune for their contracts and terminals. Intuitively I'd say that’s just not true anymore.

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.

Mark Bridge writes:

It’s claimed there’s recently been some dodgy equine activity in the mobile industry. No, I’m not talking about the dancing pony that promoted Three UK. I’m not even making lasagne jokes. I’m talking about the ‘Trojan horse’ threatening to monopolise the mobile marketplace.

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.
