I have the original iPad with a 3 G connection with at&t. I am on the Internet, and perhaps on Face Book, or other websites as well, then suddenly it throws me out of the site, a momentary black screen appears, then I am back on to the original page where the app icons are all listed when you turn on the iPad. I have to click the Safari icon to get back on the web. Why is this happening? It didn't happen when I purchased the iPad, and now it is happening on a fairly frequent basis. I was told by a person at a store that I might want to get on the iTunes site and download a possible patch if there is one, as he seemed to think it may have been caused when I downloaded the latest upgrade to the software. Is there something wrong with my particular iPad, or is it possible that some download apps did this or is it what this person suggested: the latest software download has a bug in it?

The easiest first way to try to solve ‘unexplained’ or ‘unusual’ problems with the iPad are:-

Force the offending app to close. If you have iOS 4.2 or 4.3 double-press the ‘Home’ button to bring up the multi-task bar at the bottom of the screen. Press *and hold* any icon until they start to ‘jiggle’. Then tap the top left-hand corner of the app that you want to close. It will ‘disappear’ from the list. Don’t panic - you’ve not deleted it, just closed it. Now tap the Home screen and the multi-task bar will disappear. Re-open the iPad’s app and see if the problem has resolved itself. If not, it’s on to possible solution number two!!
Restart the iPad. Press *and hold* the Power button. After a couple of seconds a slider control will appear asking you to confirm that you really want to switch the iPad off (this is all you’ll be doing). Slide the control to accept. A rotating white ‘bezel’ will appear in the iPad screen as the iPad powers down (it takes a few seconds, just like it would if you were shutting down your PC). When the screen of the iPad has gone completely blank, press *and hold* the Power button for a couple of seconds until the white Apple logo appears and the iPad starts to power up. This takes several seconds, so be patient. During the power up the automatic screen orientation function is disabled, so don’t panic. A few seconds before the power up is complete, the iPad plays a little ‘jingle’ and then you’re back to the Home screen. Restart the iPad’s app and see if the problem persists. Apple (and Forum members) recommend that you power down your iPad at least once a week, just as you might regularly completely switch off your PC. The normal procedure of just briefly pressing the Power button of the iPad merely puts it to ‘sleep’. Most Forum members have found that one of the two methods I’ve mentioned here cure a whole bunch of unexplained problems and are an easy first step to resolving most anything that happens on the iPad.

Are you still having those issues? My iPad is doing the exact same thing! I have the same version iPad that you have. I tried shutting off the applications where this happens like Tim recommended. But it doesn't help. This only started after the latest update (iCloud)
