Will Cyanogen, and other ROMs, work on the VZW nexus one? Will they have the same kernel, radio, etc.?

[Mr. Spontaneous]

I don't know whether or not the Cyanogen roms would work. I do know, however, that the radios are totally different, so you wouldn't be able to straight drop a T-Mo rom on the VZW version.

Hopefully it'll be something as trivial as swapping in some files.
