Believe it or not, I had to drive back to the Apple Store today to exchange my new iPhone for another.
The phone I originally purchased had something loose in the USB port that brought it out of charge mode with even the slightest movement of the USB cable.
I was the first person to go back to the Apple Store to report an iPhone problem, they told me, so the issue may be a rare occurrence.
The problem is, since I activated the first iPhone, activating this second one is proving to be a major hassle.
