After Nokia and Microsoft announced they had formed an alliance to make Windows Phone the primary operating system on Nokia mobile devices, many wondered what would become of the once-favored Symbian mobile OS.

Those wondering got their answer today, as Nokia recently announced it has finalized an agreement to outsource Symbian software development and support to global IT consultancy Accenture.

In addition to sending software support services to Accenture, Nokia also stated that 2,800 of its employees from around the world will join the Accenture team.

"Our collaboration with Accenture allows us to meet our ongoing commitment to support our Symbian smartphone customers and continue to leverage the talent that has the deepest experience on the platform," said Nokia vice president of Smart Devices Jo Harlow, adding that the company will explore new talent opportunities as it transitions to Windows Phone.

The deal is expected to close in October, Nokia said.

Though it has been the No. 1 mobile phone manufacturer for nearly 15 years, Nokia has struggled recently to compete with Apple and Google. According to recent figures from Canalys, Nokia's market share dropped from 39 percent to 24 percent in the first quarter of 2011.
