Take this one with a grain of salt as it hasn't been officially announced, but I received word via a reliable source today that BlackBerry's former CIO, Robin Bienfait, will be coming out of retirement soon and moving over to the competition. Specifically, she'll be taking up the roll of Chief Technology Innovations Officer at Samsung Telecommunications America.
Robin was BlackBerry's CIO from 2007 until December 2012, when her retirement was announced rather abruptly during RIM's Fiscal Q3 2013 earnings report. Her LinkedIn profile currently states that she's "In Transition".
John Sims, BlackBerry's newly-appointed President of Global Enterprise Services, recently knocked Samsung's KNOX offering on a BlackBerry blog post. His points were valid — Samsung still has a long road ahead of it in building out its mobile device service offerings for enterprise.
I think it's fair for me to say that over the years I heard plenty of "mixed reviews" on Robin. Whether this is a big gain for Samsung's mobile enterprise efforts or not, I'm not actually sure. She's definitely well known in the space with lots of connections, so if Samsung's goal is to get word of KNOX out there it certainly can't hurt.
We'll keep you updated as we learn more.
