In June we reported that Brian Wallace, RIM’s vice president of digital marketing and media, left the BlackBerry maker for greener pastures at Samsung. Now Samsung has poached another RIM exec, and this time it’s the BlackBerry PlayBook senior product manager Ryan Bidan. According to CrackBerry, Bidan recently updated his Twitter and LinkedIn profiles to reflect that he will soon serve as Samsung’s director of product marketing. The move comes about a week after Samsung saw one of its top execs also leave the firm. On July 11th Omar Khan, Samsung’s chief product technology officer announced that he was taking a new job with Citigroup.
