Sorry for my bad typing and stupid questions.. btw feel free to give me directions on what to do :]
Same process as flashing a ROM except this will NOT erase your memory. And any of these radios will work on any CDMA (which is what you have) Touch Diamond. It all depends on whee you are which on is best. I find on the TP that east coasters should use the Sprint radio, whereas people Mid-upper country should use the telus radio. Not too sure if the same applies for the Diamond, but try em out and see.
EDIT: Ok so apparently, according to the first post, a radio flash on a diamond does erase your memory. I can not confirm this since I have a TP and not a diamond, but back your info up anyways just to be safe.
