I dont believe that flashing the radio is what reverts the settings. I flashed a radio only ROM before and did not have to reprogram.

I thought the carrier customization resets the epst settings and not the flash itself, though I could be wrong. My reasoning comes from my days with the HTC touch and when the first ROMs came out, if you were flashing a different carrier based rom, you were instructed to reset before customizations or else you would have to reload your original shipped ROM and change a bunch of epst settings.
