Here's science for you:
I hold the phone in my hand, it doesn't work as a cellular phone.
I put it on the table and make a call, it works as a cellular phone.
I pick it up again, it doesn't work as a cellular phone.
Conclusion: "It's the antenna, stupid. It's borked..."
People are making way too much of this "science" crap, really. The phones are borked, if you haven't experienced issues fantastic, you're in a signal overload situation more often than not, get into a low signal area (because they do exist) and I can practically guarantee you'll experience problems
to some degree.
As has been so often noted with the Toyota brake issue analogy, it doesn't matter if every brake system failed on every Toyota, the potential for the issue (and the cases where it did fail) indicated
a flaw in the design and functionality, hence a recall of ALL of them was required.
This is no different in reality - just because you (whoever you are) may not have experienced problems, that only means you haven't
yet. The potential is there, so ALL of them are affected, hence ALL of them should be recalled.
Apple doesn't like it, and customers don't like it either, but that's just how things go sometimes. Apple doesn't have a spotless perfect record even in spite of their claims and marketing propaganda, but this time things are seriously wrong and they need to be addressed, quickly.
Even if they had to replace 2 million phones, it's a drop in the bucket to them, seriously. It's nothing in the big scheme of things, absolutely nothing at all. Few billion and change, nothing... they've been on a ~40% profit margin since 1979, let 'em use some of those billions to fix this fiasco and fast.
