Of course, iPhone 4 doesn't suffer from death-grip but death-touch, a single point of attenuation on the bottom left side. Apple made a trade-off for better overall reception and increased battery size at the expense of that single point of death-touch in low signal areas, but has since attempted to draw attention to the greater, industry-wide death-grip. (Though there's at least one video out, not from Apple, showing the new Samsung Galaxy S succumbing to a death-finger all its own.)
Meanwhile, David Chartier has started Don't Hold it Wrong, a log of similar videos as well as manuals where manufacturers point out attenuation areas on many different phones.
It's not surprising the whole "antennagate" hasn't faded away yet. It is a little surprising Apple's still adding to the attention. Video after the break.
Update: as commenters rightly point out, Apple didn't originally include Nokia on their antenna page but Nokia saw fit to make a statement about it, so now the collection has been rounded out.
