I must admit to wondering about the RF reception on the iPhone 4 when Steve Jobbs described the external antennas. To my knowledge, this is the only 'phone with such an arrangement.
Anyone with the most basic knowledge of electronics must know that the efficiency of an aerial (antenna) is effected when it's capacitance is increased when in electrical contact with another conductor, in this case, the users hand. Just listen to what happens when touching the aerial of a radio.
In areas if relatively high signal strength, the effect would not be so noticeable which could explain why some people are experiencing problems and others are not.
As far as solutions are concerned, the use of a bumper, which would act as an insulator between the hand and the iPhone, could be the answer. However, this may not be popular with some people.

I can replicate the loss of "signal" but it does not equate to a loss of reception. I've tested it with phone calls and with testing the bandwidth dozens of times. I never lose quality or drop a phone call, and quite often I have better bandwidth when the phone is showing that I have no reception.
I was up in arms about the problem until I realized it's not really a problem (at least on my phone).

I was at Best Buy earlier today and I was talking to a guy with a 3GS and an iPhone 4. I was showing them the drop in signal on my iPhone 4. The guy with the 3GS took his out and tried it and the signal dropped on his as well. The other guy who had a iPhone 4 was able to replicate as well.
I purchased a case and now it's not a problem. Still needs to be address, but at least it doesn't bother me.

I am still not sure if the signal loss is real though (or perhaps just some weird software issue).

I had a Nokia manual (for the E63) instruct me to avoid covering the bottom of the phone as it would affect the antenna.
I doubt Apple would communicate something like this because it would reveal a possible imperfection in their otherwise perfect product. I think they know and that's why they are marketing the bumpers.

I went to the apple store because I can't get my iPhone 4 yet and gripped it with my hands over the 3G band and the signal did nothing it didn't dropped and I tried this on all the phones on display. If I had to guess I think that it is possible that when you hold some iPhone 4's that way then they might lose there signal but I wouldn't worry that much about it specially if you have a case around the band like the bumper which is said to help in this problem.

I can verify that if you put a case on it that the reception isn't impacted at all and in fact does very well otherwise. However, if that is the case and you are absolutely required to have the bumpers or a case, then every iPhone should have include a bumper in the package.
There are many like me that had already ordered the bumpers and many others that were going to use a case anyway. So for me the impact is minimal, but there are others that don't like cases or bumpers. They are pretty much screwed unless they live and work under a tower!
Have any of you seen the email response from Steve Jobs on Engadget on this subject? If the email is legit, he says just don't hold the phone like that. WTF? That is his solution?

It looks like the gaps in the metal band around the phone need to be avoided while holding the phone. You have to love Apple's response.
"You're just holding the phone wrong. All mobile phones have this problem. If you can't relearn how to hold your phone, then just get a case or bumper."
