Gossip: Nokia's last ditch attempt to take on Apple and Samsung

Nokia has unveiled a new smartphone with a 41-megapixel camera in its latest bid to catch up with rivals Apple and Samsung after years of poor sales.

The Lumia 1020 runs the Windows Phone 8 operating system and has a second-generation version of the high-quality camera the Finnish phone maker first added to its PureView 808 phone last year.

It is the best smartphone camera on the market with five times more megapixels than the iPhone 5 and 2.5 times more than Samsung's 16MP camera on its S4 Zoom.
