A new study says South Africans and Kenyans are Africa’s most active Twitter users and that the social networking site is rapidly becoming a key information tool across the continent.

Researchers analyzed more than 11.5 million tweets from specific locations in Africa during the last three months of 2011.

A new report from ABI Research says the trend towards ‘freemium’ pricing on mobile apps will continue next year. The term refers to a product that’s offered free with a chargeable option for customers who want additional features or enhanced functionality.

Apple enabled in-app purchasing for free apps just over two years ago.

Not content with its efforts to put television on mobile phones, Vodafone has now launched a plug-in keyboard that turns your TV into a mobile phone.

The ‘Webbox’ is aimed at emerging markets rather than the UK, with Vodacom in South Africa preparing to start selling the Webbox next week.

A new report from Pyramid Research says more than 200 million mHealth applications are in use today, with the number expected to increase threefold by 2012.

Browser company Opera has taken a look at ‘gender equality on the mobile web’ in its latest State of the Mobile Web report. It notes that the percentage of women on the mobile web has risen 575% in the last two years. South Africa currently has the world’s highest proportion of mobile internet users – 43.5% - followed by the USA with 35.6%, Russia at 32.4% and the United Kingdom with 31.5%. At the other end of the scale, India has the fewest female users (4.0%), followed by Nigeria (5.4%), China (11.6%) and Vietnam (17.9%).

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 week we're talking about two big announcements from BlackBerry: a luxury smartphone and some major management changes.

We also discuss the latest Samsung/Apple patent ruling, Vodafone's new mobile wallet, Android licensing, Doro's anti-virus deal, BYOD and the rise of the 'selfie'.

With more than half of all pre-teen children reported to be using text messaging as their main form of mobile communication, it's not surprising to hear that bullies are taking advantage of SMS to attack their victims.

But what can mobile networks do to help these victims of cyber-bullying?  Louise O'Sullivan of Anam Technologies explains why she thinks network operators are apparently reluctant to take action - and why other organisations need to get involved.

This week's headline-grabbing product launch is the Motorola Moto G, which promises a decent Android smartphone at a very attractive price.

We also discuss new rules about mobile phones on planes, a new campaign to ban hands-free calls in cars, falling SMS revenue, mobile wallets and BlackBerry's $1 million investment.

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.

It looks like BlackBerry is safe for the moment... but not with the takeover many had expected.

Meanwhile Google launches the Nexus 5, Nortel's patents are sent into battle, EE promises ever-faster 4G, the FAA allows electronic devices to be used throughout flights and we celebrate a record quarter for smartphone shipments.
