And before anyone says "just return it", take that passive aggressive BS elsewhere. If you don't want to stand up for yourself and demand your product be fixed, don't get mad at those who have the balls to.
We both obviously want the same thing but have different views on how to get it. I respectfully disagree with you sir as you seem to fundamentally underestimate the power of returning a product, or overestimate the power of your "voice".
When it comes to consumer products the only thing that makes a difference is voting with your wallet. And returning the product does just that. It's more effective than any argument/petition/demonstration you may come up with.
If the antenna issue caused frequent and consistent call drops and disruption in data transfer to the majority of customers, then hundreds of thousands of early adopters would have flocked to return their phones. Apple would have been quick to realize their mistake and go back to the drawing boards and provide a hardware fix asap.
The truth is that yes holding the phone a certain way hampers the signal, but a signal drop per se, with no actual effect on calling and data transfer, is meaningless. That's probably why most iPhone 4 owners don't care and/or don't notice it except when actually staring at the bars.
The key fact in Today's presentation was that: iPhone 4 so far has had a lower rate of return than the 3GS. This, I believe, is the only thing Apple looked at in the end, and the only reason why they decided not to do anything about it --other than give away free bumpers.
Much to my disappointment, to be honest as I do agree they could fix this hardware flaw if they really wanted to and felt more compelled to do so based on the return figures.
Who knows, perhaps people have been holding off returning their phone until Apple officially disclosed their flight plan. Now that they've essentially said they won't do anything and that the 30 day return window is elapsing, we may see a huge increase in returns.
My advice to you: if you really want to make a difference: encourage people to return their phone even if they're not experiencing any antenna/signal related issue.
