My guess is there are (at least) two different issues. The antenna shorting issue which is (apparently) very real and a display issue which could be something as simple as a faster polling interval that shows normal RF fluctuations that don't actually impact service. The later issue is pretty common and nothing too serious -- easily fixable by a software update. I don't see how the first issue is fixable via software but it also seems like too big of a design flaw to slip through. Reports are an insulator over the gap solves the problem so I'm wondering if the original design called for some adhesive insulator to be applied to the gap and some number of units (lots or all) don't have it? I think you're right about the bumper cases though. Maybe they weren't for this specific issue but it seems to me that dents & dings on the antenna are going to be a lot more serious in the long run than just a cosmetic issue.
