Nokia will launch 12 Windows Phone devices in 2012 — and a few of them will offer dual-core processors. Speaking to Forbes during STMicroelectronics’ analyst day, STMicroelectronics’ CEO Carlo Bozotti confirmed that his company still has “very close relations” with Nokia and that it will be “an important supplier” in Nokia’s future Windows Phone products.

A few of Nokia’s phones will be powered by ST-Ericsson’s U8500 system-on-a-chip (SoC) package, which offers support ARM Cortex-A9 dual-core processors. Nokia is said to already have a Windows Phone in the works, and while the company has set a 2012 target date for its debut, Nokia’s CEO Stephen Elop has expressed interest in shipping it before the end of 2011.
