The issue is certainly real to a point... for a limited number of people in certain situations (non-case users in weak signal areas). And a smaller issue than the ways in which the antenna is BETTER than the already-good antenna on the 3G/3GS: testing showed what I myself have found: the iPhone 4 gets a better signal in weak rural areas, despite the fact that bars drop when you hold it a certain way.
Of course, bars dropping is not the same as calls dropping. That can happen too—with other phones as well—but more rarely. I never noticed by old phone dropping bars from gripping until the “scandal” made me look for it, but when I tested, sure enough it did, same as my iPhone 4. I myself have never seen a problem with touching the metal gap. Holding the bottom of the phone, yes... but I see that on other phones as well. I have no doubt there ARE situations in which touching the metal gap makes a difference, but I haven’t experienced them. The problem of actual dropped calls from the antenna design is nowhere near universal, as the drummed-up “scandal” would have you believe it to be. Unless you mean “universal” in the sense that any phone will sometimes do that...
In short, the iPhone 4’s reception is much better than plenty of other phones, but those ones are somehow OK... Well, a free bumper is no bad thing
But it’s funny... for all the vast numbers of iPhone 4 buyers on forums (where people love to complain) I don’t think I’ve ever seen anyone complain about iPhone 4 dropped calls, or return one for that reason. Ever. Not even a made-up troll! I’m sure real complaints have been made (some of them were even complaints that wouldn’t apply to every other phone)... but wouldn’t you think they’d be common? With the “scandal” making people look for a problem? I mean, complaints about little things like a mute switch on the lower-selling iPad were FAR more common. Yet all I’ve ever seen on this issue is lots of people who do NOT own an iPhone 4, indignant on our behalf. Well, thanks, but we’re fine

The problems, while real, are minor and rare.
I would never take back my old phone that couldn’t get a signal in places my iPhone 4 can!
Y'all must have great reception where you live because out here in the boonies when you only have 1 or 2 bars to begin with, holding the iPhone wrong will drop the call every time! I got my iPhone right after the case program ended so I forked out my own money to buy a case. It really helped, but I do think apple should have started providing a solution with the phone. I mean it could have been a cheap version of the bumper and they wouldn't have had any more problems.
In all likelihood, though, ANY phone would experience issues in your area; some more than others (many complex variables) and many much worse than the iPhone 4, which has been tested in rural areas and able to take calls in places the previous iPhone cannot.
And ALL phones are helped by a case/bumper (which most people have always used anyway, making this an instant non-issue for most users). Because a case gets your body mass away from the antenna. It also solves the (rare) gap-contact call-drops in the process, of course.
Apple’s problem was more a media pile-on (Foxconn-stlye!) than any fair reality. Could they have made the issue go away by handling differently? No—the media would have condemned them (in certain circles) no matter what. (Ditto with Foxconn, while other worse companies get a pass, just like phones with worse reception than the iPhone 4 get a pass.)
I'm not sure about you guys, But I did get a bumper as well, But the difference being that bumper is the biggest piece of garbage I have ever seen. It basically disintegrates and tears apart after a few weeks if not months. I would only be interested in a further replacement of it or $15 in exchange for such a cheap option given, As they are a billion dollar company and I bought a $700 Phone!
FWIW, usage varies and I don’t doubt you at all, but I’ve had mine since they were first offered, and it’s like new. I love it: it’s the case design I wished someone would make, and then Apple did!
However, I ONLY use it when I’m going to be lying it flat on a table to type/game, and only when not at home (because my table here is soft anyway). That means I use it for a few hours maybe twice a month when I’m out with friends passing it around or something. I use it naked and get great call performance the other 99% of the time. It also means I pop it on and off at least 6 times a month and it hasn’t shown wear. (When I go out with it, I must pop it on and off an extra two times to use my car dock on the 2-way drive. So I also like how painlessly it pops on and off without scuffing the phone—yet never pops off accidentally.)
I’ve also never used it for drop protection... since by bad luck, both of my iPhone’s brutal drops were caseless... but it survived both without a scratch
