In the past week in the afternoon my phone has not completed calls in or out. A call into my phone may ring only once on the callers end. I usually hear nothing but a couple of times I've heard a partial ring. When I attempt to make a call nothing happens. Doesn't matter how many bars. Then adding insult to injury I received 24 of the same text message yesterday with a new notification each time. I rushed to the At&t store in the midst of the situation and they merely reset my phone and sent me on my way. Any ideas? Is this a network or other problem that I should just live with? Is it my punishment for keeping my iPhone constantly cradled in the palm of my hand?
