Twitterrific 2.1 brings a virtual ton of new features and fixes to this powerful Twitter client. Headliners include support for recording and posting video for 3GS owners, as well as a new account picker tool for quickly finding friends’ usernames for @mentions and direct messages. There are a number of new tapping shortcuts, including options to copy the text of a tweet, add a link to Instapaper without visiting it, and shortcuts to reply or re-tweet with a double - or triple-tap.
