RIM has just released a new Flickr application for BlackBerry. The application works similar to facebook and allows users to upload photos taken with their BlackBerry to their Flickr account. You can grab your free copy of Flickr by visiting blackberry.com/flickrdownload from your device.
Flickr also allows you to geotag pictures taken, this puts your location on the picture via your BlackBerry's GPS. Details can be found here.
