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.

Today's podcast starts with a gentle warning to app developers from the Office of Fair Trading.

We then move on to Amazon's new tablets, HTC's sale of its Beats Electronics stake, Twitter's emergency alerts, UK government plans to improve mobile broadband on trains, customer complaints and the growth in adult content for mobile devices.

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.

This week's news report begins with quarterly figures from Samsung and Apple - and a discussion about what the future may hold for iOS.

We also talk about instant messaging versus SMS, the end of Best Buy's European joint venture with Carphone Warehouse, patent wars, white spaces and connected cars.
