Unless I make sure to apply pressure directly to the center of the button, it doesn't respond very accurately. On my iphone 2g I could click on the edge of the button or click anywhere really and it was always responsive. On the new phone I have to make sure that I push down at the center or else I get nothing. A little bit of a hassle when using only one hand and especially hard to get used to coming from the 2g. Are the rest of you experiencing the same?
