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?
