Hello guys, Just have a few question. I am located in india and have a nexus one non-rooted and unlocked version. I want froyo update on it but I am not able to get OTA update though update option. I’ve few question. after installing this update manually, does my N1 converted to non-rooted? what about warranty? what is the difference between this update and the public update when it will be available? can I switch back to the 2.1 after installing this upgrade ? and what happen after dialing *#*#2432546#*# ? is it harmful?
