Hi,
I am developing a system that sends breaking news, sport news… etc. this message will be sent as Instant Message (IM) to BlackBerry Messenger (BBM).

So, I need something that will be located in a server that BB user can add its PIN or email to his / her BBM, the system automatically accepts the invitation, or the system adds the BB user as new contact. Then the system sends messages to large number of BBM users.

I need how to start build this programmatically

So, how to send IM from server to BBM?
How to send / receive invitation?

You would have to write your own code on the server, and I don' believe that RIM has documented this protocol for 3rd party developers.

Also note that the BBM protocol is point-to-point and session-based.

My advice is to find another transport. Have you looked at the push API? It was designed for this type if thing.

So I have to use BES?
Can I PUSH to any BB using its PIN?
Then, I need to build BB app to be listener to show messages that arrives just from my server. Can this be done?

I think the protocol you are really looking for is Web Signals: BlackBerry - Web Signals
