THIS IS CDMA ONLY!!!
Okay. I have a VERY VERY VERY beta version built using CM6 as a base. Theme Porter seemed to do the job but there is no way for me to tell without someone attempting to flash it. I can not stress this enough, this may
BRICK YOUR PHONE!!!. I take no responsibility if it does! Maybe somebody has a busted up spare around to try first. Do a nandroid backup so if it does brick at least you can restore life back. If it works, GREAT, if it doesn't we'll need to rip it apart. You might get the CM bootscreen, not sure. Let me know. This was a 15 minute rip n' strip... Please post feedback ASAP to tell others if its at all stable or not. We don't need the whole Hero army bricking for the next few days...
