The iPhone 4's antenna is the stainless steel band that runs around the edge of the phone. The antenna for WiFi, Bluetooth, and GPS is the smaller strip beginning in the bottom left and running to the top, and the cellular radio for voice and data is the much larger strip running around almost three quarters of the phone.
Apple was going to apply an insulative coating atop the stainless steel. Perhaps even use diamond vapor deposition (like they did with the glass screen atop the iPhone 3GS) to insulate the stainless steel from users. We now know rather definitively that this isn't the case. Of course, the result is that anything conductive which bridges the gap in the bottom left couples the antennas together, detuning the precisely engineered antennas. It's a problem of impedance matching with the body as an antenna, and the additional antenna that becomes part of the equation when you touch the bottom left.
The fact of the matter is that either the most sensitive region of the antenna should have an insulative coating, or everyone should use a case. For a company that uses style heavily as a selling point, the latter isn't an option. And the former would require an unprecedented admission of fault on Apple's part.

Or possibly they wont go with... moreThis design, does improve reception. It does make room for more internal hardware elements, like battery, camera, memory, circuitry, etc. So it does have numerous benefits.
If all of then saw the BIGGER PICTURE, this could've been a major opportunity for all phonemakers to put their heads together to make this work, for it would be beneficial for everyone. Instead, they all left Apple alone in the battlefield. And yes, Apple will work this out. And when Apple proves all its detractors wrong and make this external antenna design work, how can the others adapt it when they already showed they're against it?
The iphone4 can do fine w/out a case, except for that one teenie winnie strip that degrades the signal when touched. When they figure out a way to remedy that. Apple will be the only one to deserve credit for it.

Or possibly they wont go with this antenna design anymore.
Anonymous, 20 Jul 2010In a way I'm glad that rim, nokia, htc, samsung, and motorola all reacted defensively to Apple... moreOh lordy, you are so blinded by your faith in Apple. Do you also have moist dreams about Steve Jobs? Funny how that this antenna issue came to light now suddenly all phones must have it. The human condtion is a sad one
In a way I'm glad that rim, nokia, htc, samsung, and motorola all reacted defensively to Apple's press con. I'm glad they all criticized, mocked, and DISAGREED with the iphone4's antenna design :)
Whether anyone agrees with it or not, it did prove to improve reception for the iphone. It also saved a lot of internal hardware space, making room for a bigger battery to improve battery life, and is the reason why the iphone4 is the thinnest smartphone in the world.
Only Apple DARED to risk it so they can INNOVATE. As a first attempt on this external antenna design, I say they did pretty well. When they figure out a way to make this work without a case and totally ELIMINATE THAT WEAK SPOT (all phones have it right now), let's see what the others will do :)
Oh Steve you're so evil. I think he knows and wants this kind of reaction from the media, the haters, and their competitors. Apple will push for this design and will make it work, and It would be a big year for Apple next year :)
I wonder what the others would do when Apple makes the external antenna design work, now that they all seem to think it's a ridiculous design :)
So go on haters. Enjoy it while it lasts. You guys will eat your words big time when Apple hits this right the next time :)
Anonymous, 20 Jul 2010Iphone is always techless n hopeless, apple logo is symbol of expensive lowtech stuffye, right, go get nokia:)))
and not a htc either cos they look more like a dinner plate than a smart phone
all iphone 4 customers would be beta of with two cups and a piece of string they are dyer get u selfs a 3gs or a blackberry bold

Anonymous, 20 Jul 2010Iphone is always techless n hopeless, apple logo is symbol of expensive lowtech stufftwo write mate if it had sagem write on it i dont think apple would of sold half as much as they have they look the part but for 600 u could get sumat better for half the price. bring on the blackberry bold
Oh there must be an app for that. Not as good as seeing the real deal happen though to someones iphone4. I can't explain the delight but the smile I get when I see someone find out that their Iphone4 can't do what my phone can ofc it's a few years older like. A sense of hapiness remains. Lovely ;)
Why does the Iphone only have one Monaural one signal Loudspeaker. The other is a Mic. Apparently the interview of the Sound wasn't that impressive. I hope your Iphone 4 doesn't burn to cinders. Ismoke anyone! :)
Blackberry is always better than iPhone..
iPhone is just all name no performance unit
My friend has iphone4 and i used it with him. I can not tell you that how nice and great this phone is.There is antenna problem but it occurs when you hold the phone in a specific way that is common with every phone.Beside that i advise you to go for it,it is awesome phone.
