Wrong. If I super death grip my T-mobile mytouch slide with two hands I loose one bar. My Motorola F3 was designed with antennas at both ends of the phone, so there is never a problem there. I never had a single hand placement signal loss issue with my first generation iPhone, and as far as I know my wife never had such issues with her iPhone 3G.
Bad design is bad design, period. Making excuses for Apple making such an obvious design blunder is just sad, especially when they have ~25 billion in the bank. It's not like they couldn't have afforded enough people to design this thing right.
And that is signal loss, of 1 bar. Get in a dead zone (only 1 bar showing) and you might drop a call. Never in a dead zone, you'll never care - never drop a call. THIS IS THE WHOLE argument. The 3GS suffers this too. You can have signal loss w/o seeing ANY drop in bars.
People on this site need to spend some time reading, in their entirety, including the conversations there that include engineers (some even from AT&T).

What I find so hard to believe is that people (on this site and the news sites) think 5 bars = 5 bars without understanding what's behind that representation. I loved this post that mimics my frustration:
"but since i do work for AT&T, and since i have talked to AT&T customers, i know that they DO care about the bars. i cannot tell you how many times people will tell me, "hey, i am only getting one bar on my cell phone at my office".
and i say, "well, can you make and receive calls?"
and they say, "Yes".
then i say, "well, can you connect to the internet on your phone without any problems?"
and they say, "Yes".
then i say, "well, what is the problem, then, sir?"
then they say, "but i am only getting one bar!" then i just smile to myself and try not to scream. it's almost like the famous old "who's on first" routine, but in real life."
I agree with his further comments that Apple (like Anandtech hacks into the iPhone and others for comparisons) provide the full dB readout instead of the bars. Then everyone would see the thing jumping around like crazy and they'd have to understand it's not just your hand position, it's location, objects between you and the cell tower, interference from other RF sources, etc. Then folks could argue with Apple more intelligently by saying the average dB loss in my area where I live or work is too great given the average dB signal strength of x (from the readout on their phone) provided by AT&T.
But to argue that every phone except the iPhone 4 doesn't experience any signal loss is naive.
