Requires Twitter app from AppStore
Wanna quickly post one LMGTFY link? Well, with TwitLMGTFY you can press a LMGTFY button inside Twitter.app and type anything.
Done! It will convert your text into a LMGTFY link and put it on your new tweet.
Meanwhile you can only make LMGTFY Google Search links, soon adding supports for "I'm Feeling Lucky" links.
Special thanks to Maximus.
