Sprint users....
One of you needs to take this rom, replace the build.prop, framework, and apps folder from your phone and you guys will have yourself a Sprint rom. Don't mess with anything else, and it should work. It's not all that difficult.
Or get those files/folders to me, and I can do it.
Edit: you should probably replace the etc folder as well. I would recommend the media and sounds too, otherwise ringtones and such will not work.
Easiest way to do all of this is copy out all of /system from your phone. From Aeneas, delete all Apps (except Superuser!!), audio and sounds, and then overwrite everything in system with what you took from your phone. That is your base and will leave you with Busybox, init.d and root.
