Thanks to Job's panic, I got sucked in today to a one-hour update to my
old 3G iPhone. It didn't let me know that until I was trapped.
I am not an Apple fan, even less so now.

I'm almost surprised that people use these things for voice calls any

"Old fashioned"? "OLD FASHIONED"??

I can tell you how an SD 96251 works! Given a spark coil and a

radios for hundreds of feet! I listened to "Pancho and Lefty" when
Eric von Schmidt was singing it!
I know the MORSE CODE, Dave!
