Hot on the heels of its BlackBerry Jam developer conference, Research In Motion has published its quarterly results.

Worldwide customer numbers were up to around 80 million users, with approximately 7.4 million BlackBerry smartphones and 13,000 PlayBook tablets shipped in the quarter.

Research In Motion revealed more about its forthcoming BlackBerry 10 mobile operating system at its BlackBerry Jam developer conference in California yesterday.

BlackBerry 10, which is expected to be available on new BlackBerry devices early next year, is focussed on what RIM is calling ‘BlackBerry Flow’ - the idea that a BlackBerry device won’t slow you down. For example, BB10 can show all currently-running applications as small widgets rather than simply as icons.

This week's edition of The Fonecast starts with news that Motorola Mobility is to lose around a fifth of its staff worldwide. There's also more reorganisation at Nokia, which is passing its Qt software business to Digia.

New figures from the International Data Corporation (IDC) have revealed that 85% of all smartphones shipped in the second quarter of 2012 ran either Android or Apple’s iOS.

It’s a new combined high for the two mobile operating systems, contrasting with BlackBerry and Symbian which both saw their market shares fall below 5%.
