There were several new featuresbeing added toLinkedIn's five mobile applications, and a remarkable new stat: 38% of LinkedIn's monthly unique visitors now access LinkedIn through a mobile device, up from 8% in the first quarter of 2011.</p><p>"There's two and a half times the activity on mobile compared to desktop," LinkedIn's CEO Jeff Weiner said on stage at the launch even in San Francisco. LinkedIn, he and other executives said, had been refocusing its design and monetization methods for mobile first, rather than transferring an already-established system from desktop and tweaking that. "Mobile is redefining LinkedIn," Weiner added.</p><p>The stand-out new feature wasIntro, a mobile app that allows you to see LinkedIn profiles in the iPhone Mail app, via a bar that's embedded in the email. The bar displays a LinkedIn profile picture and title, and you ca tap on it to see that person's other LinkedIn connections, their employment and education history and endorsements. The app works with accounts on Gmail, Yahoo and iCloud, but is crucially missing integration with Microsoft Exchange.</p><p>Intro joins LinkedIn's four other mobile apps, including its flagship app LinkedIn, Contacts, an app for recruiters called Recruiter and the news aggregation app Pulse.
