So, got the wife's 6682 unlocked today, after about 2 weeks of hounding Cingular... She's now using it on T-mobile, no problem with telephony. I would, however, like to un-brand it. I know that I can go to Nokia's website and flash the newest firmware, but it can't possibly be that easy, can it? What all do I need to do to remove all the Cingular crap, all of the previous owner's crap, and have the phone like it was brand new from the factory, software wise?
