Is there anyway to modify the firmware on the blackberry? I see that bigger coporations such as EMC do this a buddy of mine who had a Curve from the same carrier doesn't any of the carriers applications they install in their firmware such as "setup wizard", and "e-mail settings", the icons aren't hidden either, but I can tell from looking at the Applications installed on his phone that he has quiet a few less than me.

I looked through the BPS manuals again (the online pdf's) and there is also no mention of how to modify the service book from BPS.

Is there anything on RIM's site or can somone explain what needs to be done?

Thanks
Andrew
