So.. how is this supposed to work. There's a phone, with its main camera. It is designed to be used in both portrait and landscape modes, internal accelerometr can tell between the two. Plus you have phone with a keyboard. Common usage is portrait with keyboard closed, and landscape with keyboard open... And yes, there's linux with v4l2 working on Nokia N900.
