Just a few questions on flashing a new radio on a Sprint Hero, as I'd like to be sure I won't brick my phone and there really don't seem to be many guides on this. Are certain radios only compatible with certain ROMs? If so, what do you do if you want to flash a new ROM afterwards? In the event a radio flash fails, can you attempt to flash a different one or is your phone pretty much bricked at that point? I'll probably have more questions later, as the thought of bricking my new Hero is... well, I'd really rather not have to go back to my old BlackBerry.
