We start this week's podcast with two news stories from Ofcom. Not only has the regulator announced its plans for the UK's 4G spectrum auction, it's also released research that shows we're texting more than we talk.

There's a look at the changing relationship between HTC and Beats Electronics, O2's apology for the network outage earlier this month and the Wholesale Applications Community's integration into the GSMA.

Technology company Huawei has published financial results for the first half of 2012.

Sales revenue was up 5.1% year-on-year to CNY 102.7 billion (£10.38 billion), while operating profit reached CNY 8.79 billion. That’s a 22% drop from the same period in 2011 but an increase from the previous six months.

UK regulator Ofcom has published its plans for the launch of 4G mobile phone and mobile broadband service. It’s aiming to start the 4G spectrum auction by the end of this year.

The proposed sale will offer 80% more radio spectrum than the 2000 UK 3G auction and is equivalent to three-quarters of the mobile spectrum in use today.

Last year HTC Corporation announced a partnership and investment deal with Beats Electronics, the company behind ‘Beats by Dr. Dre’ audio products.

It’s now selling some of its stake back to the founding members of Beats, which will give the founders around 75% ownership while HTC will be left with approximately 25%.

Internet veteran Yahoo! provided last week’s biggest news, at least in terms of press coverage. It appointed Marissa Mayer as its President and Chief Executive Officer, having enticed her away from Google after 13 years.
