no, s-off is security mode off (with s-off you can flash your boot in recovery and change the splash screen and radio's) this has only been obtained for the japenese butterfly kddi.
As for the frequencies, I believe that they are staight connected to the chip set and won't be changed by a radio switch out
(In the future always look at the frequencies of your carrier and the frequencies of the phone you want before you buy it)(I have done this before, learned the hard way)
