The handset also comes with a five-megapixel rear camera with LED flash and a VGA front-facing camera for video-calling.

The Omnia W comes with Internet Explorer 9 and Bing integrated, and there are now more than 30,000 other apps available for the Windows Phone OS through the Windows Phone Marketplace.

The Omnia W comes with 8GB of internal memory.

Users can also access Windows Live Sky Drive which provides an additional 25GB of free storage for documents and media files.

The Omnia W will be made available in the UK later this year.
