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.

BlackBerry is launching Android and Apple iOS apps for its BlackBerry Messenger service this summer.

It means that free BBM instant messaging will no longer be exclusively available on BlackBerry handsets but will also work across other platforms.

Samsung Electronics and BlackBerry have both announced that some of their products have been approved for use in U.S. Department of Defense networks following testing by the Defense Information Systems Agency.

Android-powered Samsung Knox-enabled tablets and smartphones have been given approval, as have devices running BlackBerry 10. This currently covers the Samsung Galaxy S4, BlackBerry Z10, BlackBerry Q10 and BlackBerry PlayBook.

Figures from Kantar Worldpanel ComTech show that Microsoft’s Windows Phone platform is gaining market share in the UK, although Android and Apple still dominate.

The first quarter of 2013 saw Windows-based devices accounting for 7% of smartphone sales in the first quarter of 2013, up from 2.9% a year ago.

We start this week's podcast by talking about Facebook Home, the new Android-based service from the social network.

We then move on to discuss quarterly figures, a departure at HP, a mobile acquisition for Cisco, some WiFi research, the end of BBM Music... and much more.
