Yes, my phone has a "death grip". No, it's not a v4 iPhone, it's a Nokia E71. But the comforting thing is, Nokia documented it in the manual all along (page 16/17). That indicates that they knew this while designing the phone. That figures, because covering/connecting both antenna areas would require a very awkward grip. Whereas the reaction Apple displayed recently has a distinct "Oh f*ck, we forgot about that" feel to it.
