Initially, the BlackBerry Messenger or BBM, as it's more commonly known, will only support BBM chats, multi-person chats, voice note sharing, and BlackBerry Groups, where BBM users are able to set up groups to share calendar, photos, files, etc.
However, as Heins stated on stage, they have plans of making BBM as fully featured on those other platforms as possible. BlackBerry has plans to expand the functionality of the iOS and Android apps with some of the new BBM features such as Voice and video calls, Screenshare, and the just announced Channels. These will come as subsequent updates.
BBM Channels is a new way for BBM users to connect with the businesses, brands, celebrities and groups they are passionate about.
The BBM will be available to iPhones, running at least iOS 6.0, and to droids, running at least Android Ice Cream Sandwich.
*Wow this is bad market.. Blackberry has spoilt their own market by their hands. What is now the use owning a BB when I can buy an iPhone and still use BBM on it..*
They definitely ar nt stupid to hav done dat!! Ther must be a greater gain for rim
