there are few things i need to talk about the iphone4's home button.
the new design of home button is similar to the 2g iphone. you can actually feel you are clicking it (unlike 3g and 3gs which is sticky). however, my issues is even the home button is not so responsive unless you click it really really hard. if you just simply click it, the button would not work properly😡
btw, i also have the antenna issue and yellow spots issue on my new phone. the antenna issues is solved since i have the bumper installed. but the yellow spots issues is really annoying. i made appointment with apple store at 5th avenue tomorrow, and i will post apple's solution asap.
