We start this week's podcast with news that EE now has the largest 4G customer base in Europe, with 5.6 million UK connections.

There's also talk about a new DIY product for the Internet of Things, the disappearance of Nokia branded smartphones, quarterly results for Apple, increasing M2M connections and a growing market for smartwatches.

After three years at the top of the Millward Brown BrandZ Top 100 Most Valuable Brands chart, Apple has lost the number 1 position to Google.

Apple slipped to second place in 2014, whilst IBM remained in third.

The past few days have been a good time for launches. Twitter has floated on the stock exchange, Kazam has revealed its smartphone range and EE has created a tariff with a million gigabytes of mobile data.

On the other side of the coin, Acer's CEO is quitting, Vodafone UK has missed its 3G coverage target and hackers can take control of your handset's camera to ascertain PIN codes.

We started last week with a change of plan from BlackBerry. No, it’s not selling itself to Fairfax Financial. Instead it’s aiming to raise $1 billion from investors. Cynics might suggest there wasn’t enough interest for a takeover.

Twitter is valuing itself at $14.2 billion (£8.8 billion) when it launches on the New York stock exchange today. It’s pricing its Initial Public Offering of 70 million shares at $26 each, which will raise $1.82 billion.

The micro-blogging site had previous estimated a price range of $17-$20 per share and later increased that to $23-$25.

Mark Windle, head of marketing at OpenCloud, predicts that this year’s reduction in the number of traditional telecoms operators in some countries will provide an opportunity for other operators to innovate and capture market share in 2016.

He says next year will be a year of rapid change for telecoms… whether it’s MVNO disruption, competitive tariff pricing or simply defence from the ‘dark art’ of hacking.

The most memorable moments in life often go unrecorded. You don't have your camera in your hands. Your finger is still hovering over the 'pause' button on your audio recorder. Or you were simply too busy experiencing whatever was happening. It's all about the one that got away.

That's where Kapture can help.

James Rosewell shows me a colourful roll of paper that's the width of an iPhone but well over three metres long. When I look closer, I can see it's a printed copy of the Wall Street Journal's mobile website. That's a lot of scrolling to do... and a pretty unfriendly user experience for anyone reading the news online. Why does it work so badly?

This panel discussion about new mobile operating systems was recorded at Mobile Monday London on 15th July 2013.

It's chaired by Geoff Blaber of CCS Insight with contributions from the GSMA's Alex Sinclair, David Wood of Delta Wisdom (and formerly of Symbian), Andreas Constantinou from Vision Mobile, Victor Palau of Canonical and Christian Heilmann from Mozilla Corporation.

There's big news from big names this week as Nokia announces a new smartphone, Microsoft announces a new structure and Research In Motion announces a new name.

We also talk about O2 UK's backhaul deal, Apple's eBook court case, a complaint about advertising and plenty more as well.

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.

Robin Kent, operations director at Adax Europe, talks to Mark Bridge about some of the challenges facing mobile network operators as data usage increases.

They discuss how networks can differentiate their services, how can they monetise the app phenomenon, whether mobile data will kill voice and SMS... and the privacy concerns that arise around all-IP communication.

In our podcast this week we're discussing the new SmartWatch from Sony, talking about Firefox OS smartphones and contemplating Vodafone's partnership with Sainsbury's.

We're also looking at complaint figures, roaming charges, pay as you go pricing, joint ventures, BlackBerry's recent results and the future of Windows Phone.
