I've had an iPhone since almost day 1, and ever since I got it, once in a while (maybe once a week), the screen will suddenly not respond to taps anymore.. meaning I can't select a contact, but it will still respond to swipes and flicks, meaning i scroll through my contacts/music/whatever program I am in. The only way I have found to resolve it is to do a reset. If I don't reset it and just lock it and and try again later, sometimes it then works correctly, sometimes it doesn't. I sent it in to applecare a few months ago because the touch feature would stop working completely, ie. i could not answer a call that was coming in. But they couldn't duplicate the problem and sent me the same phone back. I didn't even mention this problem when I sent my phone in. I won't go to my local store (Apple Store Penn Square in OKC) because they treat me like I'm a dumbass for other reasons i've been there. Has this happened to anyone else?
