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.

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.

Microsoft have been talking about Mango, the upcoming upgrade to Windows Phone 7 incorporating their battery-friendly flavour of multi-tasking and 499 other new features. They've also welcomed Fujitsu, Acer and ZTE to the Windows Phone fold. However there was no significant news from Nokia and Microsoft. No timeframe for handsets, nothing in fact. Both companies are being tight lipped about the partnership at the moment.

This week's edition of The Fonecast takes a look at mobile payments, OS updates, SMS revenue and Bing meeting BlackBerry.

We also turn the clock back a couple of years to 2009, when former Olympic athlete Steve Backley talked to us about his mobile phone business.

It's time for another round-up of the week's mobile industry news.

Two of the recurring themes we've encountered in the last few months are legal action and partnerships. This week's legal story involves a conflict between Huawei and ZTE, while the partnership news sees RIM working with Microsoft. Yes, you may well raise your eyebrows. It seems Nokia-loving Microsoft is also a friend of the BlackBerry.
