I am having issues with keypad on the iPhone 4, new as of a month and a half ago. It is not working well, responds to the wrong touch or responds to no touch, where my finger us a mm or 2 away from the pad. I read I should take it to a Genius at the Apple Store but I bought it from ATT. Shouldn't I bring it there? I also have Applecare (which seems to be a rip-off anyway). So, what would you do?
