I don’t know about you but I’m delighted to see Sony Mobile getting plenty of coverage for its new smart watch and giant smartphone. The company’s impressive presence at Mobile World Congress 2013 showed plenty of promise... and I’d say it’s now delivering.

Network operator Telefónica has agreed to sell its Telefónica Ireland business, which trades as O2, to the Three subsidiary of Hutchison Whampoa.

The deal is worth €850 million (£722 million), with €780 million paid when the deal is completed and a further €70 million paid if financial targets are met.

Mobile Broadband Network Limited, the joint venture owned by Three UK and EE, has given Ericsson a five-year contract to manage its radio access network in the UK.

MBNL was originally formed in 2007 to provide Three and T-Mobile with better service by combining their 3G masts and associated infrastructure.

Due to growth in staff numbers my business (51Degrees.mobi) is in the process of moving offices. Coincidentally I'm also moving our home broadband. It’s not been a pleasant experience.

This got me thinking, because a few weeks ago on thefonecast.com we discussed why Ofcom isn’t treating Mobile Termination Rates (MTR) in the same way as fixed-line termination rates. The mobile industry justifies higher MTRs on the assumption that a mobile network costs more to run than a fixed-line network. It was certainly true when the fixed costs of running a mobile network had to be shared across a relatively small number of customers, even if they did pay a fortune for their contracts and terminals. Intuitively I'd say that’s just not true anymore.

In this week's podcast news report we're talking about quarterly results from BlackBerry and Three UK, we're discussing the latest network complaints data from Ofcom and we're contemplating the arrival of a new Facebook phone.

There's also time to discuss EE's UK 4G rollout, a dramatic move from T-Mobile USA and a train ticket app from O2.
