Strategic collaboration moves software activities and 3,000 employees to new partner.
It's another dramatic twist in the story of Symbian, which was originally co-owned by a group of handset makers, then went open source in the sole hands of Nokia, and has now been handed over to Accenture.
Pretty extraordinary that Nokia is effectively getting out of software development for its once-mighty OS.
Of course, Nokia still talks up the platform, adamant it will sell 150m devices this year.
But the real focus will be on WinPho following its agreement with Microsoft.
Interestingly, however, today's deal also allows for Accenture provide mobility software, business and operational services around the Windows Phone platform to Nokia.
The companies expect completion of the final agreement during summer 2011, with employees moving the end of the calendar year.
Today's deal is part of a wider re-structuring at Nokia that includes drastic job cuts.
Nokia expects the total reduction of personnel to total 4,000 employees (out of approximately 65,000 worldwide), with the majority of reductions in Denmark, Finland and the UK.
It also confirmed its target to reduce its Devices & Services operating expenses by 1 billion euros for the full year 2013.
"At Nokia, we have new clarity around our path forward, which is focused on our leadership across smart devices, mobile phones and future disruptions," said Stephen Elop, Nokia president and CEO.
"However, with this new focus, we also will face reductions in our workforce. This is a difficult reality, and we are working closely with our employees and partners to identify long-term re-employment programs for the talented people of Nokia."
