im running Build Number "2.27.651.6 CL169236 release-keys" thats what it says in the phone. iv looked online and it says right here on the htc site on this link ROM Upgrade for HTC Hero that ROM version 2.73.405.5 is available. but when i type in my serial number to download it (at the bottom of that page) it says that i cant do it. is this update for the old white hero only? or is it for the new htc hero with google for sprint also? i have the new rounded one for sprint with google, and nowheres on the internet does it say if theres a difference, and if theres not then y cant i download the new rom update with my sn? will this update mess up my phone?
