So if the signal drop is caused by the hand physically blocking antennae...

Apple is trying to convince us that this issue "exists in all smartphones" and that its caused by the hand physically blocking the antennae. Heres their education on it:

However, if the case is the hand blocking the antennae, as they want us to believe, then how come the iPhone4's signal problems can be reproduced without even touching the phone?

There are many videos of the phones antennae being shorted with a house key, part of a paper clip, etc, with the users hand nowhere near the phone. In fact, the person could stand 100 yards away and zoom in and see the signal gone with just a staple covering the black line.

Basically what I'm saying is, just because the result is similar does not mean its the same issue.

They should have announced a hardware fix, along with the bumpers for now. A simple polymer coating of the antennae, to reduce conductivity, would have fixed the problem, not required new FCC approval, and cost probably 25 cents per phone to implement.

The issue DOES exist with ALL smart phones.

So what you suggest will be enough for you, but may not be enough for someone else.

Apple said they will continue testing this and will have another re-evaluation by the end of September.

If you are not happy with what was provided today or you don't agree with it, you can return your iPhone 4 for full payment credit within 30 days of the purchase date.

Geez...

Its not about inserting metal, its about the fact that the issue is caused by something conductive bridging the gap. This means there is a fundamental hardware defect in the antennae band. I promise you you can place house keys, pennies, paperclips, etc, all over every other phone and have no issue. That means the iPhone 4's issue is different then other smart phones.

So no matter what anyone does to you, you will let it happen and not protest? No matter what Apple does, its their way or the highway?

Time to stand up for yourself. If this is a real issue, demand it be fixed.

I just posted evidence that it's a real issue. I challenge you to present a well reasoned argument that refutes my claims.

The facts are very basic:

1. Coming close to an antenna affects its impedance and its signal-carrying characteristics (ie. it can attenuate the signal) because antennas are designed and tuned assuming there are no conducting surfaces near it

2. Obviously, you cannot avoid close proximity to a cell phone antenna

3. Most other phones have the antenna surrounded by the case, so while you can get close, you are not directly contacting it

4. Apple chose to place the bare-metal antennae on the outside, where you your body (composed mostly of conducting H2O) making a direct electrical connection to them

5. To make matters worse, they placed two different antennas (cell and WiFi/BT) very close together - separated by a millimeter. Shorting those antennas is very easy to do. Not a great idea.

6. A case will keep your hands from shorting the gap, and also avoid direct electrical contact. This makes it similar to other smartphones.

So, while having the antenna act as the rim of the case sounds really cool and innovative, from an engineering efficiency standpoint it was a lousy idea.

Nope. I'm not a lover, I'm a fighter, and will gladly go to jail to beat a person's brains in - or lack thereof that needs and deserves it.

Chuck you. If I had the problem, I would return my iPhone for payment credit.

You didn't post squat. If you have a problem which you don't believe affects any other phone in the smart phone category, RETURN YOUR IPHONE FOR PAYMENT CREDIT. Don't walk, run to receive full payment credit.

Time to stand up for yourself. If you have the problem and keep your iPhone longer than 30 days, you have yourself to blame only.

Any electrical conductor can detune the antenna. Keys, staples, paper clips will do a better job than dry skin. Learn a bit of basic electricity, or RF theory before speaking about that of which you know little.
