BlackBerry 8800

I really want to make the switch to a blackberry device, as push email would make my current job a lot easier. I am really interested in both the 8800 and the Curve when it comes out on Cingular soon. However, I am a little confused on how the service is set up. I need unlimited date, text, im, and email. Is that all included in the $44.95 BB Unlimited service that Cingualr offers? It seems clear that data (surfing the web) and email are included, but I am a little unclear on the text messaging. Anyone have the service and can clear it up for me?

Thanks in advance,

Nick
