Flickr recently rolled out three new features on the insanely popular photo sharing site. There's the guest pass feature which lets you show private photosets to non-flickr users with unique URLs. Flickr has revamped their mobile site, accessible at m.flickr.com. Unfortunately, it only works for users with Yahoo! ID logins. The final feature is a pretty damn cool Camera Finder that lets you sort cameras used on Flickr by number of photos taken and such.
