Mobile phones have been hitting the mainstream news over the past few days. There was Channel 4’s report about data on second-hand phones not being properly deleted before the handsets were re-sold, there was the latest round of the Smart UK Project and there was Tim Muffett’s story about the mobile-enabled high street on BBC Breakfast this morning.

Weve - the UK mobile payment and mobile advertising venture formed by EE, O2 and Vodafone - says it’s partnering with MasterCard to speed up the development of a contactless mobile payments system.

The new system will make it easier for banks to offer ‘tap and pay’ services to mobile phone users.

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.

Weve - the mobile marketing and mobile wallet business launched in 2011 as a joint venture by EE, O2 and Vodafone - has launched a beta version of its mobile display advertising service.

The company says this means it’s just one of a few organisations that can use verified first-party data to deliver targeted mobile display advertising.
