There's a new – and free – LinkedIn app for the Blackberry. It's available to download from the Blackberry app store or from http://m.linkedin.com/blackberry/download Despite not being particular fans of LinkedIn, we've tried it: it works (always useful) – it offers full integration with Blackberry’s existing email, calendar and contacts applications – and the interface has a lot of neat touches, to the extent that the user experience is not second class when compared with the standard web browser interface.
