The jail break tools are for installing apps not the baseband perse (they let you bypass the app store and mod your phone and add non app store apps). The evasion version is meant for IOS6.x
There are I believe baseband hacks too that you would have to research on the appropriate forums. Or perhaps someone here knows a good link for you.
In order for anyone to try to help you would actually have to mention which Phone and IOS and base band version you are on.
