BlackBerry has demonstrated a new ‘over the air’ service that would allow car and commercial vehicle manufacturers to update vehicle software remotely.

The machine-to-machine (M2M) ‘Software Update Management for Automotive’ service takes advantage of the secure infrastructure that delivers software updates to BlackBerry devices.

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.

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.
