There's plenty of product news in this week's podcast, with a new Apple iPad and new tablets from Nokia and Argos as well.

We also talk about HMV's battle with the Apple App Store, new 4G tariffs from Tesco Mobile, Samsung's patent proposals and a complaint about coverage maps.

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.

There's good news for Telefonica as it's chosen to support the UK's smart meter rollout - but bad news for fans of the Microsoft Tag barcode, which is being discontinued in a couple of years' time.

We're also talking about drivers who use mobile phones illegally, Amazon's new service for mobile developers, the forthcoming Kazam smartphone, mobile advertising, satellite broadband, wearable security accessories and a word that's completely unacceptable to Motorola.

In this week's show we look at Google's new product announcements, O2's closure of its mobile telecare service and the clearance of radio frequencies for 4G services.

We also talk about the latest collection of quarterly results from Apple, Samsung, Amazon, LG and Facebook. Who's doing well - and should anyone be worried?

Nokia reveals its first two Windows Phone 8 smartphones in this week's podcast, while Amazon announces a handful of new tablets.

And if that wasn't enough, there's an update from Everything Everywhere about its plans for 4G in the UK.
