If you needed any more proof that BlackBerry Messenger is coming soon to Android and iOS then this leak should reassure you. BBNews.pl spotted the user guides for both BBM for Android and iOS. They are hosted on BlackBerrys servers and link to the apps that are not yet available. Still it does show that you will be able to send messages, location, voice messages, status, BBM Groups, and more based on your BlackBerry ID, number, or QR code. This document also says that screen sharing, voice, and video will be coming later this fall which is really sad to hear.
