I was on the radio for a few minutes this morning. Nick Ferrari on LBC 97.3 FM was talking to me about a recent survey that noted a rise in blood pressure when people received calls on their mobile phones. As I waited to go on-air, a producer asked me what I thought. “Storm in a teacup”, I said. Well, it seemed better than “Makes my blood boil”.

Nokia has had a busy few days. First came the Asha 501, a ‘smartphone lite’ that introduced developers to a new version of the company’s Asha platform. This was followed by the Lumia 928, which is a Windows Phone 8 handset exclusive to Verizon Wireless in the USA. It’s quite like the Nokia 920, so we’re not missing out too much.

Three new smartphones launched at three separate events. Yes, Nokia has definitely been busy in the past few days.

As well as talking about Finland's finest phones, we also discuss recent claims made about EE, annual results from Sony, smart metering, 5G technology, virus protection, Vodafone and the worldwide growth of mobile phones.

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.

In this special feature we're looking around the GSMA Connected City at Mobile World Congress 2013.

Mark Bridge and Grant Notman discuss machine-to-machine communications and the Internet of Things, meeting people who've worked with 4G-enabled cars, port logistics, connected houses, m-health and the GSMA's own app development programme.
