ESPOO, Finland ( TheStreet) -- Nokia ( NOK) on Wednesday unveiled its first Windows-based smartphones, the Nokia Lumia 800 and Lumia 710.

The phones, based on Windows from Microsoft ( MSFT), are part of Nokia's new smartphone strategy announced eight months ago to gain back market share from Apple's ( AAPL) iPhone and Research In Motion's ( RIMM )BlackBerry smartphones.

"Eight months ago, we shared our new strategy and today we are demonstrating clear progress of this strategy in action. We're driving innovation throughout our entire portfolio, from new smartphone experiences to ever smarter mobile phones," said Stephen Elop, Nokia President and CEO, at a Nokia event in London.

The company also launched four new mobile phones -- the Asha 300, Asha 303, Asha 200 and Asha 201 that "blur the line between smartphones and feature phones," Nokia said.
