While not part of its official plans, Nokia has unintentionally revealed an upcoming high-end media phone. A Carl Zeiss lens white paper (PDF) shows an unreleased "N86 8MP" device and clearly links the phone to the sensor and lens mentioned in the document, describing a 2952x1994 resolution and a comparatively quick f/2.9 lens with a 5.5mm wide angle. The image itself provides few indicators besides showing a conventional slider.

Regardless, photos published of a Showcase Nokia event in Singapore from this week both confirm the existence of the N86 and also point to the phone being made available in the spring.

Such a schedule would likely involve a formal unveiling in the near future, although Nokia hasn't given any immediate signs that it will venture beyond today's launches at Mobile World Congress despite a teaser image of a sample photo from the camera. [via Symbian-Guru]
