Last night, the woman next to me at the bar was having trouble with her iPhone. Calls were coming in, but the caller ID linking the phone number to the name and photo of the caller wasn't working. All she was getting was the phone number listed at the top of the screen.

I asked her when she last turn off her iPhone. She said, "Never." It stays on 24 hours a day, 7 days a week. I told her to turn off the phone.

"How?"

"The button at the top. Hold it down, wait for the red power off slider, and slide it to the right."

"I never have even seen this," she said.

We left the phone off for 5 minutes, and turned it on again - by pushing the power button on the top. The phone started up, the Apple appeared, and in a couple minutes, it was working - correctly.

Suggestion: If your phone is not working properly or if it is or is not doing something consistently, turn it off.

That seems to work much of the time.
