There's also a lot of news about mobile money, with Visa making plans for the USA, Chiltern Railways introducing m-tickets and TNS reporting a 100% increase in UK mobile banking. In addition, we talk to Yossi Yarkoni of DigiMo about his company's new mobile payment platform.

Visa Inc. has announced plans to introduce a 'digital wallet' in the United States and Canada this autumn. The service will store details for Visa and non-Visa accounts, offering NFC payments through the Visa payWave application.

In this week's edition of The Fonecast we're returning to the subject of location-tracking on iPhones. We then move on to Nokia’s reorganisation, Visa's investment in mobile payment start-up Square... and RIM's plans for BlackBerry.

We also prepare for our forthcoming 250th podcast by turning the clock back to 2008, when we spoke to virtual mobile network Blyk about its first 100,000 UK customers.

Mobile payments company Square, which offers a plug-in card reader that enables iPhone and Android users to accept credit card payments, has received a "strategic investment" from Visa.
