Quick response already, but I suppose expected with how much it's being talked about. It hasn't been a problem when I'm talking on the phone, but it is definitely an issue when I'm holding it in my left hand to use apps.

I'll let the insanity die down around the Apple Stores, and try out a bumper case this round. Been using all the previous iPhones without a case, and holding them the same way without this being an issue.
