For lack of a better term I called it a cold boot. Meaning that I held down the home button and the sleep button until it shut down, but not until the apple appeared. (Didn't know you could do that). Just until the screen was black. Then I pressed the sleep button until the apple appeared, and she booted back up.
When I did the update, I did it wirelessly (not plugged into anything). I do this at home, so it's operating through my router. I never take it anywhere.
Anyway, perhaps this is much ado about nothing because she seems to be better. Crashing only seems to happen now only when I do too much too fast.
I think it was Facebook that was having the problem..or so I heard. So thanks for your suggestions and concern.
