Default Sprit Firewall vs AOSP ROMs

I'm sure this has been asked before.. I did a little digging and didn't find what I was looking for. So the question is... When using an AOSP based ROM you do not have accessible menu options such as the ##DATA# menu as you would with TouchWiz. I wish to ask if there is such an option within the AOSP based ROM's simply to zero-out the Multimedia Firewall as it seems Sprint is blocking a large number of sites now. It also drastically helps my data speed because of my rural location. Any feed back is appreciated!
