Nokia produced the largest number of smartphones last year - but Apple generated more revenue from the smartphone market. That's the conclusion of a new report from Strategy Analytics.

The Washington Post reports that version 4.3 of the iOS Apple operating system has introduced new security for purchases made within an iPhone, iPad or iPod application. It follows complaints that children were inadvertently spending real money to buy in-app features and virtual currency.

A report in The Independent says Apple won't be putting a Near Field Communication chip in the next version of the iPhone. Although Apple is thought to be working on its own NFC service connected to iTunes, it's said to be "concerned by the lack of a clear standard across the industry".

On the surface, that phrase doesn’t make sense.

This week's edition of The Fonecast covers everything from the new iPad to O2's new content restrictions, from Android malware to Facebook messaging… and from mobile radio to Iain Graham rapping.
