what I mean is since we can flash custom radios here, can't some smart guy just develop a custom made radio that gives access to all CDMA towers? I mean I get free roaming on sprint anyways, so what's the big deal. I don't think the carrier will release the radio, I just mean a "hacked" one or whatever you want to call it, (as long as its not illegal, not sure about the legality of making your own radio with access to more towers)
