OK, so I backed out of an app by clicking the Home Button. When it went to the home screen, it just suddenly froze. Any buttons that I pressed didn't have any effect on it. I couldn't slide from screen to screen or anything. Completely frozen. So, I tried to plug it into the charger, and then it suddenly just opened up a random screen in the Internet browser. It just strangely opened up to a page I had viewed a week or two ago. And now a little circle wheel thingy is perpetually spinning in the middle as if it's about to turn off... but it isn't shutting off. And again, any buttons or touch doesn't do anything. I've tried to hold down the power button and THAT hasn't worked. So... any ideas? Thanks so much!!
