Although networks have offered spam reporting services for several years, the involvement of the ICO will increase the likelihood of offenders being identified and fined rather than simply being blocked.

Mobile coverage mapping company RootMetrics has published its latest ‘RootScore’ report for the UK. Its data, which covers the second half of 2013, shows EE as the overall winner for reliability, speed, data, calls and text messages.

Three UK was in second place, followed by O2 and then Vodafone.

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.

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.

The Financial Times reports that EE and Three have agreed an infrastructure-sharing deal for their 4G networks in the UK.

It’s expected to speed-up the rollout of 4G technology whilst also reducing costs.
