The telecommunications industry was making plenty of headlines last week – but much of it wasn’t particularly upbeat.

The debate about privacy and security continued in the wake of allegations about US agents intercepting internet traffic. Meanwhile, Nokia prepared to make its last Symbian smartphones and Tradedoubler warned that mobile devices were having a negative effect on high-street consumer loyalty.

We start this week's podcast by talking about Yahoo and Tumblr before moving on to discuss Google's recent developer conference.

There are product announcements from BlackBerry, HP and the former MeeGo developers at Jolla... and there's some interesting mobile app news as well.

Last year, the Google I/O developer conference gave us plenty of product announcements: Google Glass, the Nexus 7 tablet, the Nexus Q device and the Jelly Bean version of Android. This year’s announcements were less dramatic: a streaming music service, a Google-friendlier Galaxy S4 and some game development tools. Coincidentally (or perhaps not) Apple announced its 50 billionth app download in the middle of the event.

The past few days have seen the arrival of two familiar seasons. Not only has the sun peeked its head from behind the clouds in an approximation of Spring but the mobile industry has been releasing its quarterly results.

In our 30-minute podcast this week we're talking about the OFT's app investigation, Ofcom's plans for premium rate calls and the growth of Android malware.

We also discuss Microsoft's complaint about Google, an increase in mobile advertising and 'hacking' aircraft navigation using a smartphone.
