if ur on 3.55 OFW or lower u don't need to qa flag the console, but since ur upgrading to the 4.xxCFW's and maybe later go back couple times, just
qa flag the console on 3.55 and be done with it, u never get an accidental brick later on e.g installing a pup without the "lv1 checks" removed, for example original "kmeaw" does not include the "checks" removed, it can always happen in a hurry..right?!...qa flag it and forget it
for prefered firmwares, each like his own, all the rebugs/rogero's and the latest 4.31CFW are all good stuff
