This podcast takes a look at the issue of finance for start-ups - and, in particular, at Accelerators for tech-based companies.

It's a discussion that was recorded at Mobile Monday London earlier this week with a panel including Jon Bradford of Techstars, Simon Devonshire from Telefonica's Wayra, Diane Perlman from Microsoft Ventures and Simon Cook of DFJ Esprit.

In the past few months, the topics of security and privacy have gripped the mobile industry. The humble SMS text message has been subjected to particular attention, both on its own and in association with smartphone apps.

John Murtagh, CTO at text message specialist Anam Technologies, explains more about the risks involved with SMS, the challenges for mobile network operators and the solutions that can protect consumers.

After catching up with last week's Microsoft announcement about new CEO Satya Nadella, we go on to talk about big changes for Brightstar and Sony as well.

There's also mobile payment news from MasterCard and Weve, some patent agreements, a warning about second-hand smartphone sales, a forecast of mobile data growth and a report about app developers.

This week's podcast starts with Lenovo's purchase of the Motorola Mobility smartphone business. Was it a good deal for everyone?

We also talk about network infrastructure sharing in the UK, mobile malware, 3G coverage, misleading apps, mobile advertising, Samsung's retail plans and global tablet sales.

Patents were a very popular topic of conversation last week. Google sold its Motorola Mobility smartphone business to Lenovo but hung on to most of the patents. Does this mean the patents were the most valuable part of the business? Well, when you look at the difference between the original purchase price and the sale price, it seems a reasonable conclusion.
