hello, I need help. I want to know what is the SBEB and SBDB for?

I have a 9780 blackberry and I want to use my own service book (a modified service book). but everytime RIM refresh their network, my own SB is replace by RIM's/provider's. And it really sucks because I cant make my own SB stop refreshing. I want to protect my own SB, so there is no way it changed into another SB from RIM/provider. Please anyone help me. thank you very much.

It is not possible. Why are you modifying service books anyway?

Hacking? Only reason I can think of.
