You're missing the point...
The iPhone 4 is the first (and only) phone I know of where they have put the antenna outside the phone, with all its bare metal free for anyone to touch. No other phone manufacture has done that.
I have the phone myself - it's my first (entry level) iPhone. I figured, since I've waited this long to get one, I might as well jump in at V4 - because, one would expect by then, they've got most of the bugs and crap sorted out from the previous 3 versions. Evidently, this is not the case!
Even if I take my £5 rubber eBay case off it (I have a much better free case on order, curtsey of Apple), and grip it as shown in the videos, I can't cause the signal to drop. Having said that, I have some mains powered studio speakers on my desktop and if you put any phone close enough to them, you can hear the signal. Interestingly (just as I was in the middle of typing this message), if I hold the phone where the two separators are, I hear nothing on the speakers - let go, I then hear lots of noises.
I'm not an antenna expert, but that's enough to convince me that the phone has a problem - it doesn't appear to affect me too much, but evidently it is affecting a few. A rubber case solves the problem, in most cases.
Apple deserve to be slagged off, in my opinion. I'm mostly a PC user, but I use Apple products at work. They make nice kit, but it is, as so many people have said, style over substance. And mostly, their 'shit' keeps on breaking (lookup the number of iPods which consistently fail after a years worth of usage). And they love to charge almost 3x more for their 'style over substance' products, compared to other manufacturers.
I recently bought a Sony VAIO laptop - I wanted a high speed laptop, with Blu-Ray and HD screen. No Apple product can deliver that because they won't support blu-ray! And, it cost me about a 3rd of the price of a high end MacBook.
They deserve to get nailed. Jobs and his PR handling in this matter is appalling and if anything makes me regret buying the iPhone 4, its not because it doesn't work for me (I have a soft spot for its retina display) - it's because I seem to have purchased it from manufacture that loves dissing other manufactures to make themselves look like they are 'gods gift to mobile phones' - when, in reality, they just aren't!
Jobs, sort it out mate. You're making yourself look like a complete arrogant tw*t!
Tux - because unlike both Apple and Microsoft products, Linux just works and it is, categorically, the only OS I've come across that doesn't f**k me off and do weird 'blue-screen/freeze ups' on me for no apparent -good- reason, unlike the crap witnessed in this video:
