I seem to have solved my iPhone problem…the one I described here. When it first cropped up, I tried doing a hard reset. It didn't help. I appealed here for help. Several billion of you wrote to suggest I try doing a hard reset. Not that I really expected a different result but I tried doing another hard reset. Sure enough: Didn't work. I tried doing another and another. The sixth or seventh somehow cleared up the problem. Why? Beats the heck outta me. But it's working now so I'm not going to ask questions. Thanks, all.
