Twitter index: One Direction readies 'While We’re Young' video premiere

One Direction's latest single "While We're Young" was scheduled to be unveiled on the radio on September 20 and available to download on the 30th.

However, the finished music video for the single appeared online days ahead of the single's scheduled premiere, leading One Direction to plan a premiere on their official VEVO channel at 5pm GMT. The news has caused "VEVO" to trend in eighth position.

Also causing a buzz today is Apple's iOS 6 update which, for the first time, features Apple's own mapping service rather than Google Maps, which has appeared on iPhones since 2007. England international and Arsenal player Jack Wilshere is also trending in seventh position after undergoing his first full training session with the English Premier League after being plagued with injury problems.
