Excuse me? Not a big deal that my $1000 phone loses reception when I... hold it in my hand?
I've owned about 20 different phones now; from Nokia, Siemens, Sony Ericsson, HTC (G1) and BenQ. I remember exactly one that had a remotely similar issue like this, it was an older Nokia where the call quality would indeed reduce when you touched the upper back side with your hand (which is where the antenna was).
And let me tell you, even that was an major annoyance. Despite my hand rarely actually reaching up that far, I had quickly developed a habit to be very careful in holding the phone - always afraid to screw a call by holding it just casually.
This iPhone issue looks even more severe than that. In some of the videos it goes down to zero bars just by holding it normally.
That is simply not acceptable for a $1000 Phone. And much less for a $1000 Phone.
