To those who already dislike Apple as a company, this is like a smoking gun, a nail in the coffin, or whatever other device you want to use...
In truth, it's a very minor problem solved very easily by many inexpensive solutions. The first and least expensive for eveyone is to not hold it in such a way that causes signal loss. Failing in that, a piece of scotch tape, nearly invisible on the device would work. Probably clear nail polish would do the trick. How about that ghost armor stuff? Lots of people will get that stuff anyway.
Sure, a free bumper from Apple would also be nice, I'd really expect that really soon. Still, this won't hurt them a bit. Not even a little. I would seriously doubt there will be a recall over this. Now, if batteries start exploding, sure... there could be a recall.
Apple has some bad business practices, but they have some pretty devices out there. You know, if you look at signs concerning loud music, it's not a boom box anymore, it's a ipod. Think about that.
