I know this question makes me look stupid but i havent found any information on the guides - they just say that you have to enter the SRP host found on the CD.

To give you the background of my situation:

I have a trial version of "BES for MDS applications". During the post-installation steps, I was asked to enter the SRP address. I have no idea what this is, so i made the default (srp.it.blackberry.net)

That will work, it is based on your country. That is the connection you make to RIM to communicate with your BlackBerry Handhelds.

Why should the handheld communicate with RIM? Shouldn't the BB network be autonomous? I just cannot understand this concept. I learned from the guides that the comunication goes something like this:

Handheld --> wireless network --> MDS --> BES --> corporate network

Okay you are right except MDS, It goes
Handheld --> wireless network(RIM + TMO or whatever) <--BES --> corp network

The wireless network doesn't go looking for the BES, the BES makes the connection out.

thanks for clarifying that. in which guide can i find similar info so i won't ask 'maybe trivial' questions in the forums? thanks
