On Facebook these days there seems to be a never ending deluge of app requests, always coming in and clamoring for your attention. Most of them are junk apps. Utterly useless except as a source of income for its creators. You know these apps: these are the quizzes and endless clones you see sitting in your inbox each day.

To help you make the most of your Facebook experience, here are the the five most useful apps we know of at present.

Facebook Mobile: This program lets you send and receive messages and comments, upload new photos, and look up friend’s phone numbers, all through your mobile phone.

My Flickr: Share your Flickr photos on your Facebook profile.

MediaMaster Radio: Lets you rip your CDs and then stream them live for the enjoyment of all your Facebook friends.
