Hi again, Sorry if this has been mentioned before, I searched but I really couldn't make up my mind so I decided to ask and get you opinions. I got 2 3GSes, one is the old bootrom and the other is the new bootrom. Now since we are able to untethered JB ios 4.0, I can't make up my mind which one should I keep and which should I give away. The one with the new bootrom is perfect in condition comparing to the other. So is there any advantage for keeping the old bootrom for future JB. Or should I keep the new bootrom? Thanks in advance.
