I'm just now starting to read over this thread, and I've noticed the same issue with my 4. I realized however, that it only drops reception if i hold it in my left hand. In my right hand, it's fine.
But this is really unacceptable for a $600 gadget. Hope they find a fix.. It's so bad, that even when i'm talking ON THE PHONE while holding it in my left hand, I lose reception... what a mess.

Is your left hand much larger than the right?
 
That's EXACTLY what my iPhone 3GS is doing. Again, this is not isolated to iPhone 4's. This is also affecting older iPhones with iOS 4.

Not in the same way. Again, not in the same way. With the iPhone 4 you can leave it on the table as "literally touch with-one-finger" the black piece of the steel band and the phone drops to 1 bar. You can't do that on any other iPhone.

And in fact my old iPhone 2G NOT-RUNNING-iOS4 drops a little when you crowd it, like those examples show. The iPhone 4 doesn't have to be crowded, it only had to be barely touched in the wrong place.
 
wow I heard it works fine with the bumper on, this will require most users to buy a apple bumper

jesus christ, money hungry apple has done it again!

somewhere steve jobs is smirking on his yacht
 
NOT a software issue at ALL!!!!

I have a 3G iphone and iOS 4 installed...........NO SIGNAL reduction at all.

It's all the iPhone 4....the hardware is at fault.

But OTHERS with 3G iphone and iOS4 installed ARE experiencing the very same issue.

No, it's not. I have an iPhone 3GS with iOS 4 installed with this same exact signal reduction.
I also have an iPhone 2G with OS 3.1.3 installed with no signal reduction.
It just appears to be an isolated issue.
 
Maybe Gray Powell never discovered this during field testing because he was covering up the sides with a "3G" case.
 
isolated, unfortunately all too common. my wife's 3G with iOS4 does not suffer from that issue, tried various positions, no signal reduction.

Wouldn't it be ironic if he knew about the issue the whole time but he got fired over the lost phone before he could report it so he decided to just say eff em.
 
software

People should not use words as "certainly" or even "definitely" if they don't have a clue what they are talking about.

This might be :)cool:) as well a software issue. The antenna strength might be :)cool:) calculated from various factors and scaled to a value that represents a number of bars. The calculation and scaling formular(s) might be :)cool:) off by a certain factor.
When you touch/hold the device, RF reception changes mostly in a bad way. Without this possible erroneous calculation, people should never notice that. With this possible erroneous calculation (especially erroneous scaling of specific values), people with extremely strong signal strength could see 4.65 instead of 4.92 bars (both displayed as 5 bars), people with more fragile signal strength could see it dropping a few bars on their device.
 
sorry, had to repost this from another forum....thought it was funny:

I sent an e-mail to Steve Jobs about this problem. Here's his response:

"The iPhone 4 was never intended to be held in your hands. It is working as intended. F Adobe.

Sent from my iPhone (on my desk)"

Your 2g wouldn't experience problems with 3g signal strength regardless of software version lol.
 
My guess is this somewhat happens on olders iphones and may actually be the core reason for dropped calls on those phones.

It seemed to affect some worse than others, just like this. However I believe this is the same effect but the signal either drops lower or the code doesnt handle it as well so it results in more lost signal and dropped calls.

The chrome bezel in the 3g and 3gs was supposed to be part of the antenna system, however its a smaller surface area and not touching as directly as the iphone 4 band does so the effect may be limited because of that.
 
Is your left hand much larger than the right?

lol no. But it seems like when it's sitting in the PALM of my hand, the reception is most affected. in my right hand, where the left side of the phone is not touching my PALM, it seems to be doing fine... so weird!
 
And as a matter of fact, I hhave always had a slight impressing that putting the phone down or especially in the dock helped signal quality but I never had enough quality problems to investigate further
