If you are a FriendFeed user, then you might want to check out Webfeedr from Pine Street Enterprises. Webfeedr syncs with your FriendFeed account, allowing you to keep up to date with all your favorite websites from your iPhone.

Webfeedr (App Store link) retails for 99 cents and looks to be a great little app for keeping track of all your favorite social networking sites.
