oh my bad i might be confusing you with someone else, eh lol
im my searching i have found that The "greyscreen" problem possibly is related to touchflo. Turn it off and the problem is gone. So I think we have to wait for a fix from HTC for that. Its definatly software related cuz its on the same boat as the "Broken Screen" issue. also what custom Roms are you guys using? might be a program conflict within the Roms, just throwin ideas out there.
