CES 2012 Week In the summer of 2010, Apple's marketing was forced to move from the offensive into a defensive mode. The successful launch in June of the iPhone 4 had been quickly followed by 'Antennagate', the controversy surrounding claims that holding the handset in a certain way would kill its ability to communicate with …
"by the close proximity of an 80 per cent water human hand"
I'd be very surprised if a human hand contained 80% water. Just because a whole body does so, doesn't mean this is true for each part of it.
And just to remind you, this has nothing to do with antennagate, which was caused bu the human hand bridging the antennae who were at the outside, unprotected. Hence the 'easy' fix by isolating them with a thin rubber/silicone/... bumper.
I agree. Also, pure water is a pretty good insulator. It's all those ions in 'hand water' that cause the problems!
Re-wording the famous quote
"You're holding it wrong. You must use a hand containing only Apple-approved water"
Cough... Varicap diodes?
Cough Cough... PIN diodes?
Well, that's what they should build: A small phased array antenna for 2.4 GHz.
They could also turn around the cell-phone cancer scare: the directed radiation can be used to treat (burn) your brain cancer! Just include a brain scanner for real-time monitoring.
We hearby give notice that you should desist from posting about features of iPhone 5, or any Apple future products, and from describing in detail any technologies in pending or existing Apple patents.

Something bugs me.
I believe multiple antennas are becoming more of a necessity as more wireless features are being used *simultaneously*. For example, WiFi tethering (both sanctioned and unsanctioned) employs both the 3G/4G frequency and the WiFi frequency at the same time. I don't think one antenna could cover both roles without a lot of shuffling back and forth which could result in increased wear.
I was assuming
That this had more to do with the main cellular radio connection, of which presumably only one frequency band is used at a time.
In fact designs are already using multiple antennas deliberately to improve S/N, and thus speed, for a given power. This also involves some array phasing. How effective it is on a device that is held in the hand is moot. However, arguably, if one is using smaller antennas and they are arranged "all over" the device, one could envisage these being phased in realtime as the user waves the device around their body.
The plethora of frequencies emerging looked like it would mean that every phone would likely be tied to just one carrier - perhaps this is the saving grace that will continue to allow phone portability, and therefor wireless competition.
