If the iPhone has this (from Apple's website):

More wireless. Less space.
iPhone 3G delivers UMTS, HSDPA, GSM, Wi-Fi, EDGE, GPS, and Bluetooth 2.0 + EDR in one compact device — using only two antennas. Clever iPhone engineering integrates those antennas into a few unexpected places: the metal ring around the camera, the audio jack, the metal screen bezel, and the iPhone circuitry itself. And intelligent iPhone power management technology gives you up to 5 hours of talk time over 3G networks.2 That’s some of the best in the business.

Why not gives us the aluminum backing? Does the metal interfere with these external antennas?
 
aluminum is non magnetic so i doubt it.

It may just be a cost issue.
 
Cheaper, first and foremost. Also, I heard something about reception and/or 3G signal. Can anyone clarify?
 
The plastic "window" on the first gen is for the antenna, they went with plastic to improve reception, and give all the new antenna's a chance.

I guess until we see the tear down of the new phone we won't know. Just based on this blurb from Apple.com, it looks like all antennas are external. I am hoping for iPhone and iPhone Pro. I know keep dreaming.
 
Aluminum is why Macbook Pros don't get good wifi reception. I hear the wifi reception on Macbooks are amazing. So I assume that's another reason why they went with plastic, since the 3G iPhone has so many internal antennas.

Again, aren't those antennas internal vs. integrated into exterior components?
 
I feel like with the cost of gas going up, the aluminum is probably close to the same price so it's probably got something to do with reception.

(Plastic is made from petroleum)
 
Apple makes something in chrome... people complain.

Exactly what material could Apple use that would make it so no one complains? Carbon fiber? Hemp? Gold?
 
Apple just dropped their revenue per phone sold by $200, gotta make that money up somewhere.

Point taken, but I was not complaining, but just trying to understand. I really wanted to ask, could Apple create another iPhone "Pro" with all aluminum and get the same reception as the current 3G phone is going to have, but I knew no one could answer this question until we see the tear down of the phone to see antenna placement (if any) under the plastic. Based on the reading above, it is all external.

unobtainium
 
real reason is cost of aluminum right now is just climbing at a very quick rate with +10% increases in cost multiple months in a row. Metal cost a lot now and is going up so I am not surprised to see them dumb that cost from some where.
 
Any good conductor will shield radio waves, and aluminum is a very good conductor.

OMG! You know what's a non-conducting material that would make a super cool enclosure material? Glass! Imagine if the whole thing were wrapped in the same strong scratch resistant glass that they use for the screen! You'd be able to see through it just like you could see through the original iMac's case!
 
Oh great, then we'll have people complaining their iPhone is not termite-proof.

Yeah, but wood is way more durable than that cheap old plastic they're using. Only downside is that you may get a few splinters here and there, but hey! That's a small price to pay. If the iPhone were made of wood, it'd probably be cheaper than $199!!! [end sarcasm]
 
Why not some sort of new blend metals like titanium or magnesium alloy, carbon-nanotube-weave, composite ceramic? I honestly wouldn't mind carbon fiber...but only if it's painted, and I can't see the texture.

Then maybe you'll enjoy this.

Or rather, you'd hate it, because it gives you the look of carbon fiber, but not the benefit.
 
I know for a fact that the Bluetooth/WiFi antenna and the 3G antenna are on opposite ends of the device (one is on top, one is on bottom).
The distance allowed it to meet a certain FCC requirement. Therefore, the old design with just plastic where the antennas were wouldn't work.
