YES! F*****G YES! I'm already S-OFF'd via the XTC-Clip, but gonna do this unlock anyways.
12:45am where I live, and this just made my day!
EDIT 1: I kept getting "model ID" errors, so I had to extract the rom.zip from the RUU.exe and apply it manually from HBOOT.
EDIT 2: Just a tip, the recovery can be fastboot flashed. From what I've read in the Wildfire S section, boot.img's will need to be fastboot flashed too if you didn't S-OFF via the XTC-Clip.
EDIT 3: Seems like you can fastboot flash everything but radios and HBOOTs - I fastboot flashed a boot.img and a system.img of a nandroid backup of the 1.54.401.2 stock ROM - I could see this being very useful.
