Last month, we noted that Apple has owned the iTun.es domain since December 2006 and with Apple rolling out Twitter integration for its Ping social networking service speculated that Apple could use the domain as a link shortener.

One month later, Apple has done just that. Users sharing links to iTunes Store content to Twitter will now see iTun.es being used to generate the links for their Tweets. Third-party Twitter applications may, however, continue to display Twitter's default "t.co" shortened version.
