Rumor has it that RIM is currently in talks to acquire Gist, a startup created by ex-Microsoft TA McCann. The company collects profiles about people in your business network by scraping data from sources such as Rapleaf. The social profile is displayed alongside when the contact emails you, much like Xobni does for your Outlook inbox. The acquisition could have some interesting implications for your BlackBerry Address Book, and perhaps the success of Xobni tipped someone off at RIM that this sort of social inbox should be native on the device. Overall, it looks like RIM is really ramping up its acquisitions.
