a quick question, probably been asked before somewhere else or something, but i just want a concrete answer if possible.........if i go ahead and flash to get GB up and running on my thrill, it COMPLETELY possible to go back exactly to stock froyo, using the official AT&T files and baseband etc, etc?? cause that seems to be my worry as there is a thread that has every other .kdz file except for the AT&T one, which leads me to believe that it is not possible to go back to normal if things dont work out with GB...im anxious to go to GB as there are much more ROMS for it and 3D words as it should, but some are having trouble getting 4g, and other just dont get it at all....i dont mind flashing and doing all of that, as i came from a Sony Xperia X10, that was officially stuck with Eclair as far as AT&T is concerned, but the great devs over there were able to get GB working great for our stateside X10a's.....just wanna know
