BlackBerry Chat enables real time conversations among BlackBerry, Android and iOS users. You will be able to see if your message has been delivered and read, and you will be able to tell if the person you are conversing with is responding to your message. You can also share photos and voice files. And with BBM, groups of up to 30 can communicate at one time. You can even share pictures and schedules.
With BBM, users can post a profile and a picture and users can instantly receive your status update. And right now there are 60 million BlackBerry members alone, averaging 90 minutes of use daily. More than 10 billion messages are sent and received each day, twice as many as are sent and received through other mobile messaging apps.
BlackBerry's announcement did not say anything about an alleged 3 month exclusivity period that Samsung's Android devices were rumored to be receiving.
