Why doesn't cingular support this feature?? Every other carrier does. Can someone explain to me why? Will this feature work on the 8300??

It works on all Cingular BlackBerry's. By not supporting it - they mean don't call them with any problems you're having with it.

It works!!

Does it work on the 8300?

I don't think it works on Cingular that well - it doesn't let me add Blackberry subscribers with Cingular just outside of Cingular. Can anyone explain that?

I have not heard of that issue.

It's an issue when I was trying to add contacts - it was weird. It would keep them in a pending friend state. I just got frustrated and deleted the app.

Does it use SMS or Data anyway?

Data.

I BBM with fellow Cingular users all the time, including users on here.

And incidentally, this has been covered in the following threads:

...including this one, with almost the exact same title as yours...

Blackberry Messenger Not Supported By Cingular!!!!!!

On lieu of Pizzle's last post I deem this thread closed!
