[ROM FILES] Official RUU Android 2.2 FROYO - Build 3.26.651.6 [and RUU app]
I extracted out the rom.zip from the RUU and here's the link to them.
Mediashare link - 3.26.651.6 rom.zip
These are the Official 2.2 ROM files - they are essentially the same stuff found in the PC36IMG.zip images posted around. They are not rooted.
Here's the file listing, unformatted (file size, file date/time, file name):

The 2nd link is the RUU application used to flash to scratch the Evo from a Windows machine, instead of using the manual zip, bootloader process. If you have ever used a Windows mobile phone, this is that same process. You just put the rom.zip file (must be that name) and put it in the same folder as the application.
MegaUpload - RUU app
This could be used to do Part 1 of the whole rooting process. It could also be used (I believe) to possibly do the entire rooting process in one swift flash. figure this would be helpful so that we [actual devs - not me] can/could create flashable RUU ROMs like we used to with WindowsMobile phones and like we used to with the Samsung Moment and Sprint's update utility.
EDIT: The rom.zip is signed by Sprint, so I believe all the rom.zips that were to be used would have to be signed - but not sure.
