Just bought mine last night, selling my 3G now. I bought a case with it, I don't get dropped signals

It's funny how my Verizon iPhone doesn't do that at all. I actually went from 4 bars to 5 while doing the death grip. I really miss my Droid though.

I have tried it with my desire, holding it every way i can and the bars stay the same as it would if i wasnt holding it...
I own an Iphone 4 and I have never lost signal anywhere in the city. So this is mostly a myth. The IP4 does have pretty good signal. On the other hand; I did have some cell phones that lost signal in a few places.

Sure if you are in a terrible reception area you are likely to lose signal with any phone. However my IP4 has never failed me yet.

The signal for my iPhone 4 is awful..
I get this all the time in town centres/my house etc and in the country-side it goes up?

I would ask for a replacement if I were you. I find my signal to be better than other phones I had. On my Sony Ericsson my calls would drop so much at my place. With the Iphone 4, they never do.

Although it isn't evidence to anyone but myself, when I hold my 3GS it drops between 10 and 25 dBm usually somewhere in the middle; even if the 4 did drop 20 dBm it wouldn't be a big deal for me.

You said it was an intentional aesthetic design decision that results in this issue, but if it was such a simple fix why do you think Apple wouldn't have done it? It's not like they aren't very experienced engineers.

For over a year they tested this phone and its antenna, surely if it was as simple as putting a coating on it that they'd have done it?
Yes, the iPhone 4 performs better than previous generations at lower signal strengths. However, the fundamental design flaw still exists.

Analogy: The new car model gets a 40HP increase.... but also gets a parachute. Wouldn't you perfer to get rid of that additional drag?

Apple did "fix" it.... they gave out the bumper casings for a few months. What is rubber but a dieletric material insulating your meat sack (i.e. hand) from contacting the antennas.

The problem I see with a coating is that it needs to be very resilent (withstand scratching, wear, and rubbing off) while being clear or aesthetically pleasing.

Apple instead gave out the bumpers till the issue died down. They also knew that they would be going to Verizon which would help reduce AT&T network strain as well. Basically, they held off criticism until people forgot/did not care.

From a technical/engineering prespective, it is very sloppy... but who cares as long as it looks nice, right?

I'm not saying the iPhone is without flaws, I just think the issue is completely overblown because of Apple's status in the tech industry. The problem can't be too severe for either phone, otherwise there'd be an awful high return rate and there hasn't been, at least for AT&T; we'll have to wait for Verizon.

At the end of the day it's consumers that make or break these phones and decide if their worth keeping, not videos of death-grips and death-hugs and rating and raving on forums. My point is, if the iPhone is more prone to signal degradation and/or loss, it's clearly not a problem for consumers, therefore is it a problem at all?
I am only discussing that fact from a technical/engineering prespective. The Verizon phone still uses two external antennas? Then it has the same issue. However, broadcast engineers could tweak the antennas' shape and location to help reduce the issue.

I am tying not to bring in any externalities or the overall design of the phone/OS/ecosystem as many of those aspects are subjective. However, this design issue is NOT subjective.

...but you don't understand the issue. You are attempt to use your individual case and subjective testing to support your point of view.

However, widespread testing confirms the issue. When I say testing, it MUST include the debug screen with the dB information to be valid.

Furthermore, physics provides the causation.... antenna detuning.

Did Apple really claim to fix the antenna issues? David Pogue himself admitted (shocker!) that the Verizon iPhone still had these "death grip" issues in his preview a couple weeks ago. I understand ignoring the problem, but I doubt Apple told a blatant lie, saying they had fixed the "death grip" problem for good.

Basically,
I thought one of the difference between the verizon and at&t iphone was the position of the antenna. I did read in one of the reviews that apple relocated the position to prevent an easy bridging between the antenna. (Or at least I thought I read so)

I guess it is easy to bridge the antenna if you make sure your hand covers the entire phone. (although there are plenty of phones out there than loses some signal if you grip it completely)

Sure, but does the improvement not further level it out towards that of other smart phones? Additionally, when used with a case does it not provide a slight advantage over other smart phones?

I'm interested to see whether Apple furthers the range the iPhone 5 can hold onto a signal down further to something like -129 dBm vs -121 dBm on the iPhone 4. I think that's what they're going for, but I might be wrong.

Of course, but if the signal strength is similar to before it shouldn't be a problem. Use with a case though, should technically "get rid of that additional drag".

I believe they gave out the bumpers to counter the massive amount of negative press they were getting. The majority of the negative attention about the iPhone 4 was due to it losing most of its bars when held, which was for the most part to do with how they were calculating the bars.

I truly think if it wasn't for the "software issue", this would have received no where near as much attention as it did.

The way I see it is, the iPhone 4 performs very similarly in terms of signal strength to the 3GS, if not a little better and, with a case it has even better signal strength. And no, I think both are important, I wouldn't buy a product that's deadly ugly that works nor one that looks fantastic and doesn't work.

agreed. I tried my GF's V iphone and it doesnt do the death grip problem at all. It might, but not anywhere near as bad as mine does from launch with AT&T. It didn't drop any bars at all (it might be loosing signal but not as significant to drop bars consecutively) whereas my phone drops 3 if not 4 without a case.

In fact, I've read alot that Apple has fixed most of the death grip issues with recent iPhone 4 production. Engadget says they find it hard to replicate the death grip problem with newer iPhone 4s. If you were to buy a new AT&T iPhone 4, supposedly alot of people are reporting it isn't as bad as launch models. So I guess I have a collector's piece huh
