Twitter has started to roll out a new version of Twitter.com for mobile devices. Most people who use Twitter on a smartphone opt for one of the official apps or a third-party app such as TweetDeck rather than the browser, but the the new mobile site promises to improve the experience for those without an app.

The new mobile browser is currently only available to a limited number of iPhone, iPod Touch, and Android smartphones, Twitter announced on its blog, but there will be a full roll out “in the coming weeks”.

Judging from the pictures released by Twitter, changes include the black navigation icon bar along the top.
