I'm going to try this now heh.. will report back shortly. I took a look at a video online and it appears that the ring is accessible once the glass is removed...

so I just took that little o-ring out. wtf is it there for? lol, it was almost off the lens anyway. I only pried it open enough to get a needle in and take the ring out, I didn't take the whole thing off. I doubt it's as water resistant but who knows...
ADDITION: so it appears to narrow the field of view slightly. I don't take selfies, I may have a hangouts video call once a week (usually on my computer, but if I'm out I'd like to be able to do this..). I notice if my finger goes over the edge of the top of phone (but not over lens) it pics up my finger, where as it wouldn't have before.. big deal. I'd rather not have to take it apart again, so the ring is gone lol.
I hit it with the hair dryer once after pressing it down... going to do it again shortly, its' completely cooled. just hitting it again to be on the safe side. didn't cause any damage to phone so was rather easy just make sure to be patient. I had pry tools from old phones, but I wouldn't recommend taking the entire glass off with it...
