Ultimate D3 w/ US GSM & CDMA

[flemdroid]

So, as my backup GSM phone just crapped out (Unlocked Samsung 'Blackjack') I start pondering of D3 potential. Do people think theres a way to custom edit some files like the radio.img to enable the harnessing of US GSM bands while simultaneously preserving access to big reds 3g airwaves. I ask this because I have to use my overseas sim card once every couple months so it doesnt get deactivated. How much time could it require?

Thanks
Eric
