iPhone 4 Signal Declines While Being Held? A Longstanding Phenomenon?
Gizmodo has compiled a series of videos demonstrating that the iPhone 4s single bars seem to drop down significantly when being held in hand. The report actually began in our own forums with a video demonstrating the reproducibility of the problem:
The finding has generated many responses from people who have noticed similar behavior. While there has been some talk of this being a display error rather than an actual signal issue, several have reported that calls do drop when the bars decline. At least one user has posted a video demonstrating it not happening on his iPhone 4:
While this reader dismisses the claims as "trolling", there are plenty of videos from a variety of users demonstrating the reproducibility on many other people's iPhone 4s.
The question, though, remains -- is this a new issue or are people more acutely aware of it due to the attention drawn to the iPhone 4s exterior antennas. One expert had even predicted this might be a problem.
We're not so sure it's an iPhone 4 specific issue. We remember seeing videos demonstrating this same issue for prior iPhone devices. For whatever reason, those videos never drew that much attention. Here's a video showing the same phenomenon on an iPhone 3G. This video was posted in 2008:

i'm not overly surprised. you create three separate antennas on the case, each one is most likely "tuned" to the frequency range it's supposed to operate in, and you short them to each other in your hand and change their characteristic impedance. the body is a high resistance, but it just may have an affect.

doesn't happen here in Switzerland with my iphone 3g. Maybe a AT&T issue?
nor have i heard of dropped calls etc. here in Switzerland.

Its an issue with the iPhone itself, and not AT&T.
Here is a thread about it.

This is a known problem with all iPhone models, actually. The signal declines when being held, when being looked at, when going between apps, when sitting on a desk, when driving, and during a variety of activities.
The iPhone and AT&T network are designed to show a full 5 bars until you actually try using it go on the internet.

Yes. AT&T sucks.
In this case it's not AT&T. If you hit the bottom and left corner, the call drops.
