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.

Nokia has launched a new Windows Phone 8 smartphone in London this morning. It’s called the Nokia Lumia 925 and is described as ‘a new interpretation’ of the Nokia Lumia 920.

Unlike the previous flagship device, the Lumia 925 is lighter and has a partly metal body along with an AMOLED screen.

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.

Nokia’s new flagship Lumia 928 device - described by the company as “a new expression of the world’s most innovative smartphone” - has been announced today.

It’s launching as an exclusive product to Verizon Wireless in the USA.

Nokia has introduced a new handset that’s being described as “the first of a new family of Asha smartphones”.

The Nokia Asha 501 runs a new Asha platform that’ll be compatible with other Asha devices in the future. This means application developers will be able to create apps for the new smartphone family, taking advantage of the Nokia application store and Nokia’s forthcoming in-app payments tool.
