Default how to upgrade to hboot 2.16

I want to try liberty rom and it needs newer hboot. I have a really old hboot and i wonder how/where to get a new one. And are there any disadvantages with the 2.16 hboot? Because i remember in the past my old hboot was good because i wiuld flash radios even with s-on. But now im s-off so maybe it doesnt even matter...just asking.^^
