Flickr has rolled out a brand new version of its Windows Phone app. The app takes advantage of the Windows Phone 7.5 Mango firmware and new features include a built-in camera, composure grid and focus assist.

The app allows you to upload images in the background and switch between apps quickly, while the performance is faster. You’ll now be able to take advantage of the in-app camera to take photos and share them to Flickr directly.

The composure grid lets you add a grid overlay on your screen to help you compose and align your shots. The grid will turn green when your image is in focus. Photos that you capture are now saved to your Pictures Hub in addition to Flickr.

The app allows you to pin new tiles to your phone’s Start screen to let you access the in-app camera, your recent activity and your Flickr photostream faster.

The update to this app follows on from the launch of Flickr’s Android app last week. It was revealed Wednesday that Flickr now hosts more than 200 million Creative Commons licensed photos.

You can download the latest version of the app on your Windows Phone device now.
