I got a 16g and she got a 8...Totally new to ATT. I am discovering a problem with mine. My home button does not respond immediately. If I am in an app and I hit the home button, sometimes it does nothing. I have to hit it again, sometimes three times and it goes back. If I really put pressure on it it'll go the first time. The button doesnt have the click feeling when you press it. My wifes does and you can often hear her push it. Mine has none of that. Can I take it back to exchange with ATT or do I have to find an Apple store? Little thing like this is bothering me.
