Anyway, here's what I did if it saves anyone the trouble:
1) Install RSD lite. If you don't know what this is, or haven't done this before,
use these awesome directions.
2)
Download 4.1.83 sbf ... FYI the owner of this link claims that he did not sign an NDA and therefore NDA restrictions do not apply.
3) Use RSD lite to flash 4.1.83
4) Use
Gingerbreak to root
5) Use
Gladenable for sideloading & custom tethering
So, the reason why I went this method was because I had totally screwed with the stuff in my /system/apps in my .57 ROM and and I didn't want to take an OTA. Moreover, actually I couldn't d/l an OTA... said no updates were available.
Anywho, hopefully this is helpful for someone out there who hasn't gotten their OTA yet, or for those that want to root with .83 and had made changes to /system like me.
Disclaimer: If you screw things up, it's your own fault...

Good news is, with RSD you can probably unbrick most anything.
