Unfortunately, it's not interoperable with Blackberry (yet?), but the functionality is identical.
I'm not sure why you posted this answer as it has nothing to do with the question posted.
Blackberry messenger does indeed not work on the PocketPC, but there are other messenger apps for WindowsMobile. I use IM+ by Shape Services but there are countless others. Sadly none of these will do pin to pin communications, so you'd be stuck with the large IM networks only.
