+1 but I'm pretty much done with these forums... I don't even consider myself an Apple fanboy, but there's so much negativity around here I can't take it anymore.
I love my phone. Can I force it to drop a call by intentionally holding it a certain way, without a case, in an already low signal area? Yes. What did I choose to do about that? I called up AT&T, the one responsible for the low signal area, and asked a manager for a free Microcell. He was happy to give me one. Between that and the bumper (which I had planned to purchase long ago anyway), I'm more than satisfied.
In fact, the only reason I've been following this circus and worrying over it is because I keep coming back to these forums. Looking over the threads, you would think the world is ending. What we have is a VOCAL MINORITY of the world population who have become the majority on this forum. Why? Because they're either convincing happy users to be unhappy, or because happy users are out enjoying their phone.
So other than checking in here for white iPhone 4 rumors for my wife, I'm done here. It's too much of a downer. For those of you who are genuinely unhappy because you have problems using the phone under REAL WORLD conditions, I'm sorry, this isn't directed at you. I'd politely suggest that you exchange/return your phone and deal with AppleCare directly (over the phone preferably). They want to make you happy and if you're polite, they won't stop trying until you are satisfied.
