First, to our very loyal users we are sorry for any confusion this week. Thank you for being patient and allowing us to set the record straight on the details and user impact necessitated by the coming split of BBM into three separate services: BBM Enterprise for all devices; BBM Consumer for BBOS and BB10; and BBM Consumer for Android, iOS and Microsoft devices.Why We Are Making Changes: For several years, BBM has been serving two very distinct and different audiences: enterprise customers, many of whom require military-grade security for their text, voice and video conversations; and consumer users interested in a free service that offers sticky features like games, shopping, music, news, payments and more.
