Blackberry Messenger on the iPhone

Hi, i was wondering if anyone knows of a way to run or communicate with blackberry messenger in the iPhone. I suppose this is not possible because you should have an active Blackberry PIN but maybe some one discovered a way to bypass this.
I saw a video of a guy that run BB Messenger but doing a remote desktop of another phone which is not practical or performant at all
Thanks

It would be nice if someone finds out a way... maybe if you have a blackberry plan, and a bb pin (from your old blackberry) someone can bypass the server and be able to connect to bbm...

Just wondering...
