Radios only improve your reception in your location and do not affect the ROM you are using. I have tried a few radios and some tend to eat up battery life. Others may disagree but in a nutshell it how it works for you. As for unlocking the sim, this is done so that you can use any carrier sim in your phone, again has nothing to do with the ROM you use. Its a nice perk to have to be able to do these and the hard work the people have done to make this possible is why I paid the money. They deserve it.
