Except alot of people, who previously had no problems, are experiencing signal loss when they are in areas where the AT&T coverage is not excellent. The evidence pointing towards it being a flaw in all released phones is becoming overwhelming.
wow are you serious? no one is saying there aren't problems. some people are having them and some aren't. so now its time to try to find root cause, and it is pretty safe to say the answer won't be simple, there are combination of factors here
also, keep in mind 2 things have changed, but hardware and software, so just because someone says they don't have a problem with the old phone and do with the new doesn't put the blame solely on the hardware, since the software changed as well.
like i said, some have a problem, some don't, sorry to those who do, either wait for apple to find a fix or return the damn phone, no one is forcing you to keep it. put your money where your mouth is so to speak, from apple's perspective reading this they must be smiling on the inside because despite all the dissatisfaction no one is willing to return their phone, in fact they almost sold 2 million of them.
