Nokia plans to launch only one Linux smartphone in 2010, according to reports.
This is contrary to analyst expectations that the Finnish company would roll-out a raft of Linux phones in the next year to counter competition from Apple's iPhone.
But Nokia appears set to revamp its Linux Maemo operating system first to make full use of Qt technology, which enables one application to run on different operating systems.
Nokia is also said to be aiming to improve Maemo's iPhone-like capacitive touchscreen support and integration with Nokia's online services.
The company plans to upgrade the Symbian operating system in the next six to 18 months, despite rumours that it would be phasing it out.
Nokia remains "firmly committed to Symbian as our smartphone platform of choice," according to a company spokesman.
Nokia is expected to cut another 220 jobs as part of further plans to reduce research and development activities in Japan, bringing the total worldwide R&D job cuts to 550.
But Nokia marketing head Anssi Vanjoki has dismissed speculation that the company has plans to sell its manufacturing plants.
"Our logistics and manufacturing are an important competitive advantage, and a core part of Nokia's business. We have no plans to change this business model," he said in a statement.
