Congratulations! Welcome to the beautiful and powerful darkside!
Now, you read and re-read. Eventually, you decide what you want to do, then cautiously execute it. Repeat after me:
"I am a concientious device owner. I acknowledge that my device and I are capable of more than is expected of commoners. I have chosen a different path than that a mere consumer, accepting responsibility for my actions and indulging in the rewards of my newfound enlightenment. With this power, I embrace the responsibility it carries. I hereby absolve my carrier of responsibility for my actions and forgive its representitives of their ignorance, as they do not obstruct me in my path. I promise to conduct due process of research in my install of new software, accepting and publishing bugs as they present themselves. I hold those who code their ideas in esteem and not fault, respecting their sense of benevolence. I shall not install ROM Manager, for it is the demon crutch of the weak and the swift vehicle to the state of brick. Should my path lead me to any sort of rapture, I promise to provide a logcat of the experience, denying no user or developer such blessing, in accordance with the GPL and those who revere it. nAndroid then Android always... mod on."
