[citation][nom]Ragnar-Kon[/nom]The problem is not with the service, but with the phone. True that AT&T's service is crappy, but the drop in signal due to gripping the phone in a "wrong" way has to do with the phone itself, not AT&T's service.[/citation]
It's people like you that cause all of this.
Let me ask you something, do you own the iPhone4? I am going to guess that you don't. I happen to own the iPhone4, and although I can make the bars drop, it never actually drops the call, and this is to be expected and can be reproduced with other smart ones as well.
I have only ever dropped calls in NYC, which IS due to the service.
Please get your facts straight, get off the damn hate-Apple-wagon, and smarten up. You look like an asshat.
