Just an observation ;-) Prompted mainly by the strange pointless dig at the Nexus One which had no relevance to the conversation or OP.
I don't think the dig was pointless. I'm not an EE kind of guy, but from my understanding, basically all modern cell phones can have their antennas interfered with through touching the bottom of your phone. But the way that the iPhone 4's case was designed increased the severity of the interference... my Nexus One does the same sort of thing. Just yesterday, I was talking on the phone, and when I tried to hold it with my shoulder rather than with my hands, I was told that I "sounded like I was underwater." This is almost 100% reproducible.
I think the first time I tried holding it on my shoulder I dropped it so never held it like that again :-D
