LinkedIn has launched some updates for its iPhone, Android and iPad apps.

In a post on the LinkedIn blog, Joff Redfern writes, “1year, 21 days ago we launched an entirely new LinkedIn mobile experience for iPhone, Android, and the mobile web at touch.linkedin.com. It was an entirely fresh start, focused on faster, simpler, better.”

“A lot has happened since then,” he adds. “A year ago, 10% of the unique users visiting LinkedIn were using one of our mobile apps, today it’s over 23%. In April, we gave birth to an iPad app, and in May we followed with a shiny new Windows Phone App that is rated 4.5 out of 5 stars. We’ve also made it easier to sign-up for LinkedIn directly from your mobile device, which now accounts for 15% of new member sign-ups.”

New features for the iPhone and Android apps include: new real-time notifications when someone likes what you’ve shared on LinkedIn, views your profile, accepts your invitation, etc., company pages for mobile, and access to job listings from within your mobile update streams, in case you “don’t want your employer to know you’re looking.”

The iPad app is now supported in French, German, Italian, Spanish, Brazilian Portuguese and Korean, and also gets the notifications and company pages.

While not available yet, LinkedIn says the ability to edit your profile from the mobile apps is coming soon.

Here’s a look at the new company pages that will be rolling out this year.
