So I took an iPad 3 in today for a dodgy home button problem. One of the things the Genius mentioned is that this could be caused by software corruption. He asked me if I ever force close applications, and when I told him that I did he said "don't ever ever do that, it can corrupt your software". I was a bit taken aback by this, because I have always force closed my apps this way if needed (apps with bugs causing battery drain, etc). He showed me the alternate way of closing an app by using the top button on the iPad in conjunction with the home button to terminate the app. Is there actually a difference in the way apps terminate depending on which of these methods is used? Does this guy know what the heck he is talking about? It seems that every time I go into the Apple store the experience gets stranger.
