Nokia has announced a premium smartphone that has 18 carat gold-plated highlights, a sapphire crystal for the home key and Caledonian leather on the back.

It runs the latest Symbian Anna OS with a 3.5-inch reinforced glass AMOLED display, an 8-megapixel camera with 720p video recording, 3G HSDPA and WiFi.

This week's podcast from TheFonecast.com covers the 'Quick Tap' mobile payment service from Orange, the new mobile OS update from Microsoft, the ultra-small SIM proposal from Apple and the termination rate complaints from almost everyone.

We also announce some changes to our programmes.

Mobile payments hit the headlines again, with Orange and Barclays announcing 'Quick Tap' - and O2 also revealing its plans. In addition we discuss an OS update for Windows Phone, an even smaller SIM for iPhones and an appeal against mobile termination rates by almost everyone.

Ofcom's recent reduction of mobile termination rates is bearing fruit at BT. The company is cutting the cost of landline-to-mobile telephone calls from 28th May.

Evening calls will fall from 7p per minute to 5.3p when ringing major UK mobile networks from a BT line, which represents a 24% cut. Daytime calls are down 13% from 13p per minute to 11.3p.

Microsoft has officially previewed the next major release of the Windows Phone 7 platform. It's code-named 'Mango' and will include more than 500 new features.

This update will be available free to existing Windows Phone 7 customers and is expected to be included on new phones from the autumn. Those new phones will be produced by Microsoft's existing partners - including Nokia - and by new manufacturers including Acer, Fujitsu and ZTE.
