I get much better reception than her in bad areas. I also get much better reception and network switching while travelling.

The same is true of the iPhone 4. It's just easy to find the exact place where it happens on the iPhone because it's basically marked.

A lot of people now vaguely have an impression that the iPhone 4 has spotty reception. That impression will last much longer than if Apple had attacked immediately with these videos instead of "there is no problem".
But keep it all in perspective eh?
Just yesterday on the beach a friend was snapping a photo of the sunset with his iPhone 4, saying wow this thing really takes great photos. He also mentioned being concerned about the antenna issue. Yet he was oggling it like it was a jewel. Others present bemoaned not having had the foresight to pre-order.
Later in the afternoon another friend was wandering around ranting "where is my iPhone 4!" in increasingly loud and frantic tones, until finally he found it and was reunited with his precious.
