None of those pictures in Apple's marketing materials represents the "death grip." The "death grip" isn't just a matter of holding the phone in your left hand. It's holding the phone in such a way that completely covers a tiny spot on the left hand corner in a sustained fashion.
You do realize the "spot" causing the problems is the seam between the two antennas on the lower left side, right?
What you and so many other folks are getting wrong is that
it doesn't take any special type of grip that is outside of what people would "normally" do when holding the phone in the left hand - and in some instance, the right, because their fingers on the right hand can bridge that seam/groove/notch exactly the same.
In my experience, with the iPhone 4 I have sitting here on my desktop beside me, it doesn't matter if I hold the phone normally in my left hand (the seam is bridged by contact with the skin of my left palm) or the right hand (the seam is bridged by contact with one of my fingers as it wraps around the left side of the phone) and the 3G capability of the phone is neutered, in under a minute, with complete loss of service.
People focus on "death grip" or some other way of stating it thinking it means holding the phone in a way that is contrary to the way most anyone with a cell phone would hold such a device in their left hand (or even the right as I just described). There is no "death grip" - only a label that simply means
holding the phone in your hand, period.
Note that in these images, I am not going to focus on the so-called 3G signal since they're probably attached to a microcell for the recording purposes...
The focus of these images is on the way the iPhone 4 is being held, which pretty much everyone should agree is "normal" for effectively everyone on the planet (as long as you do have a left hand, of course - no slight or offense meant towards those that may be so encumbered). There's no "death grip" going on here, and the grip shown, the way these images depict the iPhone 4 should be held, is how I and most everyone else hold it when it's in the left hand, and not on a phone call (that's another story).
It's not about "dropped calls" - that's just a small part of it, actually, as people will spend more time with the phone in their hand utilizing the apps and capabilities of the phone that utilize the wireless networking (either by cellular data or Wi-Fi and perhaps even Bluetooth as required). Do you surf the web with Safari with the phone up next to your face? Nope, you don't,
you do that with the phone in your hand with a grip that is pretty much going to be just like everyone else.
It's all about showing how the phone is supposed to be held, by design, by marketing materials, by actual demonstration of the iPhone 4 in use, and nothing more.
These are the facts, and they cannot be disputed.
Need some proof?
