I'm just afraid of VZ or Sammy pushing thru an update that'll close all the loopholes the devs were able to exploit, which is why I rooted and flashed right away. Also, make sure you backup your IMEI before you start flashing, it will save you from a potential headache down the road! This is different than making a nandroid backup in recovery (you should do that too, though). Its very easy, follow the steps here:

I used Terminal Emulator method once I was rooted.
