If you have ever used a jailbroken iPod or iPhone, you may have used TuneWiki. Lyrical (App Store) uses the new access to the now playing to give you similar functionality. When you have a data connection (WiFi or 3G/EDGE), this app will lookup the lyrics for the current song. Lyrical is free, and works well from my experience. If you are not currently playing a song, you may still lookup the lyrics by selecting a song from your library. There is also an option to search for lyrics to a song you do not currently have. Lyrical is a great app for anyone running 3.0 on their iPhone or iPod touch!
