BT has won a Supreme Court ruling that could see it reclaiming millions of pounds from UK mobile network operators.

In this week's podcast we talk about two of the big announcements from Google I/O: a new version of Android and the retail launch of smartwatches powered by 'Android Wear'.

Ofcom has published the volume of complaints made against mobile phone network operators, fixed-line phone providers, broadband companies and pay TV services between January and March 2014.

Iain, James and Mark then move on to discuss luxury smartphones, a new handset on the high street, mobile broadband for aircraft passengers, government monitoring, the growth of smartphones - and 4G-equipped donkeys.
