I'm afraid my ignorance about Blackberry technology is showing here.

OK, you need to try to understand something, because you're missing a very important aspect of this whole BlackBerry thing.
** BlackBerry Data uses RIM's Network... not the Internet. **

Your BlackBerry Server connects to RIM's NOC via SRP on port 3101 TCP.
Your BlackBerry Device connects to RIM's Network by means of your wireless carrier's data network.

Your BlackBerry Device does not talk directly to your BlackBerry Server over the Internet.
All BlackBerry Data traffic is transmitted over RIM's network.

In an oversimplified nutshell:
Device <--> Wireless Carrier <--> RIM BlackBerry Infrastructure <--> RIM Noc <--> BlackBerry Server <--> Messaging Platform.
