Please say yes. Please oh please say yes.

I've read around the internet that there's an "opt out" option for updates, where you can manually download updates without waiting for carriers to roll them out, at the expense of losing your warranty.

Does such a thing really exist? Or am I just dreaming of a perfect world without OEM bottlenecks (again)?
