iPhone users will abandon iMessage for BlackBerry Messenger… Wait, what?

Just when you think we got rid of the RIM co-CEOs, Mike Lazaridis comes back.

BlackBerry (BBRY) founder Mike Lazaridis said he’s confident that users of iPhones and other devices will embrace the company’s BlackBerry Messenger platform, which will be offered on rival phones later this year.

“BBM is by far the most compelling wireless experience and wireless social-networking environment,” Lazaridis, who stepped down as co-chief executive officer in early 2012, said yesterday at the Bloomberg Canada Economic Summit in Toronto.
