A new report from Juniper Research forecasts that one in eight mobile phone users worldwide will either have a 'mobile ticket' delivered to their phone or will buy a ticket using their phone by 2015. That's over 750 million users, compared with 230 million people today.

The next two years are expected to see mobile ticketing become mainstream, with mobile barcode boarding passes and cinema tickets leading the way.

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.

In this week's podcast we discuss the iPad 2, data restrictions, mobile radio, mobile viruses and mobile tickets. In addition, Leslie Ferry of Broadsoft talks about IP communications... and Iain Graham raps. Yes, really.
