How to reset everything to factory to resell phone

[gatorbri]

I am getting a new HTC Droid Incredible this weekend and want to be able to resell my HTC Touch Diamond on eBay or Craigslist. What do I need to do to reset everything? Do I just re-flash the original Alltel ROM? I know somebody posted that up here a while back, but can anybody give me a link to that again?

Do I also need to reflash the original Alltel Radio? Or will that automatically happen when flashing the original Alltel ROM? If not, can somebody give me a link to the original Alltel Radio as well?

Thanks so much for all the great ROMs and help I've used from you guys while owning the Touch Diamond!
