For me this whole deathgrip issue isn't that big a deal, because I don't have an i4.
Seriously Apple has handled this very poorly. They had a known issue, didn't fix it, then they handled the PR poorly. Now they are putting out this video that says "See others are doing it also". No the problem is your phone. Worry about your hardware and stop being a pathetic little child. You had an existing issue with reception and didn't take care of it. This would have been such a big deal if you weren't a bunch of arrogant jackasses.
