This may play out like the last OTA update that mysteriously appeared, then just as quickly disappeared from Google's servers, but we're hearing that the OTA is pushing, so you might want to check your phone and see if it finds an update itself. Hopefully, this is the real deal and we can go from worrying about when the update will come and get back to complaining about the update like we're supposed to do. I kid, I kid.
For instruction on what to do if you're rooted and ROM'd, be sure to hit the Verizon G Nex forums and read a bit -- everything you want or need can be found there. Our fingers are crossed this time!
